Just want some info for my setup.

I plan to get an AMD Phenom II 720 AM3 chip. I'm hearing of the 955 AM3 quad core this April, but not sure if it's black edition or price, so should I just stick with the 720?

I don't want to spend a ton of cash, but I want this thing to laugh at most, if not every game it tries, and laugh at every game coming in the next year.

I don't do anything but gaming, other than internet browsing. I plan to buy a 1080p HDTV in the coming months and would like to hook up to it.

So for the best bang for the buck, there are a few parts I'm not sure about.

Video card - I'm thinking maybe an ATI 4850x2, or 4870 then maybe crossfire later, or maybe even the new 4890. On the Nvidia side, 275-285, somewhere in that range. $200-$300 price range there.

Motherboard - Not real sure for AM2+ or AM3, and ram to go with it. I'd like the option to overclock, possibly even unlock the 4th core of the 720. Does Asus or Gigabyte allow the ACC option for unlocking it? I'm not sure about Crossfire or SLI because something inside me says it's more complicated than a single GPU and I like to keep things easy, but it might be convenient to have the option down the road. I am a brand name guy too, so anything unfamiliar scares me.

Case, PSU - Some people say,"Get a 1000w PSU". I'm no PSU pro, but that seems like overkill for my system. I don't put a lot of things in it. CPU, memory, vid card (one preferably), DVD burner, Hard drive. That's it...maybe a sound card too. And with the case, I want good air flow for overclocking, but don't want to spend $200 on a metal frame for my components. Something in the $50 range is good.

Fan - Again for potential overclocking, but I don't want to spend more than $40-$50 on a fan, less is better.

I'd prefer keeping the whole system build around $750, but could stretch to about $1000 if the bang is worth the buck.


So, my patience is running thin. I'd love to get this going real soon, but don't want to be too hasty. Any advice is very appreciated.

About unlocking the 4th core, I've been hearing that you need the ACC option for your bios and Biostar and Gigabyte have those, but any other brands? Do I just need the SB750 and the 790FX, GX, or X northbridge, or does the brand name matter for that?

(of course I'm not expecting to, but hoping)

I think any board with the SB750 will do it, but I can't guarantee that. I would stick to a good brand though, Gigabyte is one of the best.

Try doing something like this:
Ram
720 and Gigabyte AM3 Board combo

If you plan on OC'ing though, I wouldn't recommend unlocking the 4th core. It was disabled for a reason, if that core was stable then AMD would have sold the chip as a PII 920 instead of a 720. At the manufacturing plant the chips are tested for quality control. If a chip has a defective core then they disable it so it won't affect stability. To be honest though you don't really need that 4th core for gaming anyways, just OC the three cores you have and you will get better results.

But there is no harm in trying to unlock the 4th core, right? If it doesn't work, I could just reset the bios and keep the setting where it was. Nothing bad happens to the hardware, right? So why wouldn't you try to unlock it?

You might get a stable 4th core at stock speeds, but if you overclock I am willing to bet it will be unstable. Unlocking the 4th core would pretty much mean you can't overclock, which will show more performance gains than having the extra core at stock speeds. If it doesn't work out for you then you can just set it back to factory settings and there will be no harm done (I think...)

Either way, I'm stoked. That chip shows some good numbers even stock, so it should last me a little while without too many crying moments that I can't play something.
