Hey, um a while back I built a gaming desktop that cost me around three grand at the time. Recently I've been using a laptop but I really want to rebuild my old computer and upgrade it. Just wondering if you guys could help me with some of the parts.

Case-
My old case is very beat up and was wondering if anyone knew a sub 100$ case with good cooling.

Graphics Card-
I was going to go for the Geforce 9800 X2 considering gpu is the most important part when gaming.

Power Supply-
I found http://www.newegg.com/Product/Prod [...] 817341002. Was wondering if 700W is enough.

CPU-
I was thinking http://www.newegg.com/Product/Prod [...] 819115037. I currently have an AMD 4200 x2, I was wondering if it would be a huge hit if I kept the 4200. Money is an issue, but I could get that cpu if necessary.

Motherboard-
I was wondering if anyone knew a good cheap motherboard that matches the linked cpu above.

Hardrive- I was thinking of getting a very cheap 7200 RPM hardrive. I was wondering if 10000 rpm would improve my significantly. I was looking at http://www.newegg.com/Product/Prod [...] 822144102. (I have an external harddrive so space isnt an issue)

Ram- Was looking at http://www.newegg.com/Product/Prod [...] 820146726. Also wondering if 4 gigs is necessary or if i could go cheap and just get 2 gbs.

Thanks, any help would be greatly appreciated.

the Antec 300 is also nice.
The OCZ GamexStream 700w is fine
the E8400 ? or the E7200 ? both are good, E7200 overclocks well

@OP What is your budget?

For PSU go with the PP&C 750, also consider the Corsair 750TX. If not doing SLI/CrossFire get a PP&C 610 or a Corsair 550.

Don't get the 9800X2. Get a ATI 4850/4870. The X2 4200 should be fine for now. It may be a bottle neck and you might loose a few FPS.

For HDD get a Seagate/WD 7200.11 500GB+ HDD.

Not sure how much RAM you have now or what factor (DDR or DDR2) but 4GB should help.

Providing you are doing a complete re build and willing to OC and want to keep the cost down:

P35-DS3L(budget) or P45-DS3L(mid) or P45-DS3R(for CrossFire). [All the boards listed OC very well]

E2180 (until you have $ to upgrade, easily OC to 3Ghz) or E7200/E8400/Q6600 depending on budget

PP&C 610/Corsair 550 (for single GPU) or PP&C 750 for SLI/CrossFire.

ATI 4850 wins hands down for price vs. performance

4GB (2*2GB) DDR2 800 from Corsair, G.Skill, Crucial, or other good brand.

500GB 7200.11 HDD

XIGMATEK S1283.

Thanks. I looked up the ATI 4850/4870 and found them to be cheaper. Do they receive better or around the same fps as the 9800 x2?
Also I've decided to stick with the 4200 and just overclock it.

I have a K8 Triton Nforce4 in my old computer that I'm upgrading. Do you think I could just keep that? And if the ATI cards would be compatible.

Thanks for you help.

Yes. They should be cheaper and the FPS are usually only 3-8fps lower than a 9800X2. And yes it is 100% compatible with your chipset, but to be honest that chipset is old.
