I am considering upgrading but not really sure which way to go. I am torn between getting a new Opty 170 CPU or waiting towards the end of the year and just getting another 7800GT to complete the SLI. I was just a little worried from seeing the game benchmarks that difference seems very small between 1 and 2 cards. I just really don't want to pay $350 to get 5 more FPS. If anyone has used 7800GT in single and SLI could let me know if it is worth getting.

Yes that is why I'm torn I really want a dual core but was considering waiting for the AM2 release in June hoping they would drop the price a little on the current versions. Maybe sneak in on a Opty 175.

I posted a link to an opty review here. Good stuff.
IMO go dual core. Get an opty 165, and OC it. Newegg has 165's for $332 shipped and 170's for $419 shipped. Read the review, 165 is the way to go.
Some games benefit from dual core now, and the rest will soon. Use the money you save to put toward the next gen of graphic cards, which will beat an SLI current gen setup for sure. Unless dual cards (ala SLI or Crossfire) mature very rapidly, which I doubt, it is pointless.
Dual core support, on the other hand, is inevitable. You will be glad you did.
As far as AM2, why bother? You want performance now. Future proof? Dual core.
Economic feasibility? In 9 months, which would be easier to dump on eBay: two last gen 7800GTs or a MSI board with an opty that is "guaranteed to over clock to XXXX"?
-just my 2 pennies.

You might want to update that, I think you mean $342 on the 165. No way are you gonna find it for 242. If you did, I'd buy them all and send them to eBay for a quick buck. Plus the link shows them as $328 plus $3 shipping.

CPU upgrade will probably give you better total system performance, and dual core is the way to go (makes a huge difference IMHO). The 7800 GT should be able to handle what you throw at it at the moment with a good CPU, the worst case being you need to turn down AA or the resolution a little bit. You'll get more out of waiting for the next gen cards to come out in a year than you will with SLI now, while the CPU will probably last you longer.

In my experience (louched of friends) SLI tends to give a performance increase between -10% and +30%, +40% if you lucky. That does not nearly match with the price and not to mention the power draw etc. etc.

I would go for the Opty, you'll see a bigger performance gain, and Yay for ocing!

SLI was a gimick used by Nvidia to sell more cards basically, no thought really for what it could do for performance.

If you get a SLI setup, and your games support SLI, your minimum (weighted) frame rate will rise considerably.

Moving to a dual-core would also help there aswell, but not as much. (Very few games minimum frame rates benefit from multi-core systems).

The upshot of SLI is you can port it to a new mobo later on,... the CPUs value will drop off sharply by Q3 2006, the video cards value will drop aswell by then, just by not as much.

From a reseller value perspective in 6-12 months, and also from a minimum weighted frame rate perspective (assuming games benefit) going SLI may actually provide a better overall system experience today, while maximizing reseller value tomorrow.

Still a tough choice either way, do you do anything besides gaming that will benefit from the dual-core ?

It seems like the general consensus is to go for the Opty. I would like to try some mild overclocking not crazy but maybe bump the 170 up to 2.4ghz. I have only used stock cooling in the past can anyone suggest an excellent air cooling setup.

Thanks for all the responses.

The opty 165 is an excellent choice and just use the stock cooler that comes with it. Its excellent. I installed it using AS5 and temps are awesome. There is a drawback to using the stock cooler and that is, it is noisy compared to my zalman cooler on my Intel machine. Doesn't bother me though.

The reason I was looking at the 170 vs 165 is the 10x multiplier. I would prefer the 165 and just overclock it. But I seem to have a difficult time gettting over 220 FSB with my setup. I don't know if its the ram, the mobo, the processor, or more likely me. But even loosening the timings up to 3.4.4.8 and lower the HTT to 4x it is still unstable. I bumped the vcore up a little more but didn't help. Should I try lowering the DDR from 400 to 333mhz? Thats the part that confuses me, if you lower the DDR speed isn't that lowering the FSB too? I also hear people talk about the memory divider but I don't see that in my bios and I don't really know what it does. I see people with like yourself with 250+ FSB and my ram (2x1gig OCZ Platinum) is suppose to be overclockable (maybe not that high), I'm sure I am doing something wrong. Any ideas?

I'm with everyone else, get the opty. One caviat, if you like to run 16x12 with eye candy then that's what SLI is for. Anything less is a waste IMHO.

get the opty 165 or 170. The new stock cooler is all you need, I have my 165 running @ 2.8ghz with 1.45volts temps idle 34-35c full load both cores 46-47cc

You have a pretty good CPU for gaming. Your bottleneck is the video card. Most new games aren't very CPU-demanding...
He has a bottle neck?

I would've thought the 7800GT would be more than adequate at the moment.

It depends how you look at it. Obviously he want to improve his gaming experience and then a better video card is the way to go.

Personally I would think a 7800GT is more than enough to satisfy my gaming needs...

what resoultion do you plan on playing your games at, cause higher res play will be far more dependent on the video card, and works very well with sli, while gaming under 1024x768 will be more dependant on the cpu, figure that out and you have your answer. 8)

and yeah one 7800gt should be more than enough, as well, your cpu looks pretty good as well, really don't know why your considering an upgrade already, money to blow? :p :?

You certainly have a lot more moolah than me - I'm still on a 6600GT! :D

So basically to me price vs performance is very important, and in that respect SLI is totally not worth it.

Really it would be better to sell you 7800GT in a x months and get an up to date single card.

6600 GT? HAH! AIW 9800 Pro AGP baby!! But then, the games I play aren't really graphics intensive. At least until Elder Scrolls Oblivion comes out.
