I'm under budget with this build as is, but I wouldn't be opposed to saving even a little more without sacrificing too much potential. As mentioned, all suggestions are welcome, and much appreciated, and if there is a better build out there for less I'd like to know.

I'm usually an AMD kind of guy, but we use the i5/i7's at work and I have to say I'm impressed so I figured I'd test waters with Intel this time around, not saying if there is a superior build for an AMD gaming rig in the same ballpark I wouldn't like to know.

Thanks in Advance,

Jason.

I think you have too much emphasis on the processor and not enough on the video card. You also can scale down some on the power supply.

I'd base it around an i3-540 and one of the Asus P7P55D boards. I'd also replace the Seagate with a Western Digital Black. The lowest end video card I'd use would be a Radeon 5770 (Asus, Diamond, or HIS). 500 quality watts is enough - Antec, Corsair, or Seasonic. I do question Mushkin - I prefer Corsair, Crucial, Kingston, or A-Data ram.

Thanks for the input, I was going with what I've experienced as far as processors go by the one I use at work.

I'll switch my spec. out to the WD caviar black, the 4 year longer warranty is worth the extra $20 alone. Thanks for mentioning that change.

I see what you mean about the Radeon 5570, more bang for my buck, and the price difference is minuscule. Thank you!

The only reason I also went with a larger PSU was because of the possibility of adding a second graphics card in SLI/Xfire mode when I got the extra money. Would a 500 watt PSU eventually run two of the Radeon 5570 cards or should I stick with the 650 watt PSU in that case?

A quick question about the i3-540 and the Asus P7P55D board, do you think they would handle Crysis as well as the quadcore i5, I've been playing it at work and I'm addicted.

If we're only talking a slight difference in performance then I'd love to save all that money by going with the cpu/mobo you mentioned.

I agree about the ram wholeheartedly, save for Kingston -- even if they no longer have their ducks out of whack -- they've done me wrong so many times and the customer service wasn't very friendly, the only reason I went with Mushkin was they really seem to have good customer service reading the reviews on Newegg.com though I think I will go with the Crucial ram I looked at first. Never had a problem with that brand before.

Look forward to more responses!
