First Build, Need Help - $400 Budget Gaming PC

APPROXIMATE PURCHASE DATE: Next week; Payday BUDGET RANGE: $500 and under ($400-450 preferable)

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming, Web Browsing, Multimedia

PARTS NOT REQUIRED: OS, Monitor, Speakers, Keyboard, Mouse, Hard Drive, DVD Drive, Aftermarket Cooler

PREFERRED WEBSITE(S) FOR PARTS: None; I chose all my parts from Newegg but I'll buy from anywhere offering the best bang for the buck.

PARTS PREFERENCES: None

OVERCLOCKING: Yes, but not to a serious degree, experimentation mainly SLI OR CROSSFIRE: No

MONITOR RESOLUTION: 1024x768

ADDITIONAL COMMENTS: Is this functional? I'm trying to be as budget as possible and despite what I've heard about getting a good namebrand PSU, will the 585W one that comes with the case be enough for the 4870?

Also, someone told me the RAM is incompatible with the chipset of the mobo's chipset because it's 2.1V and the G31 chipset supports only 1.8V. He recommended:

OCZ Blade Series 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Desktop Memory - Retail

Despite researching on google, I could find nothing to support what he said, so is this true

Grand Total: $415.15 (without rebates)

So my main questions are: Is this build functional? What specs will this build be able to play Crysis at? Should I just buy some higher quality items in the areas of the case and PSU? Also, I only chose the mobo because it came with the CPU in a combo deal, any better suggestions would be great.

Just please, give me any help you can while keeping the price in the $400 to $500 range.

Based on your resolution I think the card is overkill.

I recommend going with a 4850 to save cash, then choose a different case/psu.

If you buy a strong name brand PSU now, then in a year or six months or whenever you have the money/desire you can upgrade your monitor/gpu and not have to worry.

Thanks for input, I think if I did downgrade on the GPU from a 4870 I would choose a 9800GTX+ rather than a 4850 based on reviews I've read on newegg, but idk that build does sound pretty good. And I know Corsair is good but could that 400W power supply really handle a 4890? And the reason I chose an Intel build was because from every source I've read AMD cannot even compete with Intel in the dual-core processor range although their new quad-cores are becoming competitive.

my poor uninformed friend let me show you something

amd boards are cheaper
upgrading amd is easier
and "real men use real cores"
observe

isnt it strange this $110 amd x2 250
http://www.newegg.com/Product/Prod [...] k=x2%20250

is so close in performance to this $190 intel e8500
http://www.newegg.com/Product/Prod [...] 6819115036

tell me is .31 frames per second worth $80 , if so then by all means go intel

SILVERSTONE SUGO SG02 - $69.99
Intel Pentium E5200 - $69.99
CORSAIR 550VX / GIGABYTE GA-G31M-ES2L - $142.98
G.SKILL 4GB DDR2 800 - $47.99
XFX GTX 260 Core 216 - $184.99

Total: $515.94 | After Rebates: $455.94

This is getting the most out of your money while only going $15 over budget, which actually won't exist after you get your rebates. Since you are gaming you want a strong graphics card.. The XFX GTX 260 is on sale with rebates and two games, why not? I also found a sweet combo on a 550VX and GA-G31M-ES2L.

The mobo is mATX so naturally I went to find a nice case to fit it, I already had one in mind. The SG02 is a beautiful micro-atx case that fits a regular sized psu and video card.

Last to do was ram, it was easy.. G.SKILL has a strong quality and low prices, if you want some 1066 ram, spend about $10 more for the same brand.

Any objections to this build?

As far as Intel vs AMD, let's say it this way, I've been working on computers for probably 10-11 years, I've got my Bachelor's for IT, and I've got my Apple certification, but I have always used AMD, reason being I can't justify the price differences between the chips, because personally I work hard for my money and can't see throwing say 50 bucks away on the intel chip that may be 5% better. But so far I've not been dissapointed by AMD. As others said, if you have money to spend, thats one thing, but when you are on a budget you want the most balanced system you can, there is no sense in having a gaming system with a faster processor but not have as much memory or have a bad video card. Better to have a worse processor, but have more ram and better video, etc.
