Upgrading from an Athlon Xp 2900 ! Help!


Dec 4, 2008
:hello: It's been about 5 years since I built my first PC and now it's time for an upgrade. It will be used for gaming and I do want to overclock. This is what I'm thinking of going with so far based on some research I did. I'd like for as many suggestions on my list and recommendations. I really want to order all this stuff by Wednesday the 25th. Budget is around $800 maybe more. Should I go with Vista or stay with XP? Any suggestions are appreciated. Thanks.

I'm not sure what memory to get or heatsink for CPU. Any suggestions?
I already have a 22" LCD (1680x1050), 2 big hard drives, and I will probably use my old pioneer dvd burner.

$10 more gets you a Corsair 650TX. With that PSu you will be able to do Crossfire when/if you need to. Your case and MB and video card already support it.

That's an excellent MB, by the way.

If it's mostly for gaming, and you don't play FSX or GTA4, change the Q6600 to E8500.

Heatsink: Xigmatek Dark Knight.

The HIS card has only 512MB, but that's OK for 1680x1050. It's also cheaper, has a free game, and has the best reviews. I'd pick that one.

G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 900 $55


G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 $55
I hadn't seen Proximon's post yet. 100% agreed with both S75CF and HD 4870, if the budget allows.

I noticed a combo at Newegg for Antec 900 and P5Q Pro, $30 off. The P5Q Pro is very similar to the GA-EP45-UD3P.

Thanks for the suggestions Proximon. I think I will go with the S75CF and HD 4870. Thanks for the suggestion Aevm, but I do plan on playing GTA4 and I want to multitask while gaming. I will be getting one of those G.Skill kits, but I think I will stick with the Gigabyte MB. Thanks for help guys. One more questions, what OS are you guys running, Vista or XP?
I'd go with the 1GB MSI 4870. As for the heatsink it's a matter of preference but I would go with something like this XIGMATEK XP-S964


For cooler selection you may want to do your own research to see which coolers are worth it and which really aren't. X-bit labs does a number of cooler reviews so you may want to check it out, especially if you want to get the maximum overclock from your Q6600 as in that event every last bit of cooler performance is important. with Xigmatek rifle coolers you may also want to consider getting the retention back plate as some of the models do not come with it.


While that 500W PSU should be able to handle the load I think you may be pushing it a little if you decide to crossfire with two 4850s. If you want to crossfires with two 4870s I would seriously suggest getting a more powerful PSU such as a 600W+ unit from the likes of Corsair or FSP.

For a gaming box I'd recommend Vista Home Premium SP1 64-bit OEM. It gives you DirectX 10 and full access to the 4GB of RAM (or even more if you add more sticks later.)

Your other major option is XP 32-bit, which will see 3.5 GB or less and plays games in DirectX 9 mode (i.e. some games look the same and some look less good).

XP does have an advantage: old devices (printer, scanner, etc.) may not have drivers for Vista at all.

It is bigger, it's 120 mm instead of 92 mm. Be careful, if you get the HDT-S1283 you need a different retention bracket, called ACK-I7751.

Thanks for all the suggestions Aevm, I will be getting that bracket. I might have to get Vista to play games in DirectX 10. What OS do you use?

Vista 64 Home Premium ftw. It reads all 4 gigs of memory and utilizes DirectX 10. Newegg has the builders edition (OEM) for $100 + free shipping.
