Need Help Finishing Build

[hoch721]

Today there was a deal on buy.com for a EVGA GeForce GTX 280 SC 1GB GDDR3 512-bit PCI-E SLI Supported Video Card for 210.00 USD. I've been thinking of building a new computer, so I went ahead and got it. Now, I need some help finishing the rest of the cpu. I'd like to keep it on a medium budget, while at the same time taking advantage of the video card's power. Some possibilities I'm considering are:

CPU:
Intel E5200
Intel E7300
AMD 6000+

After I decide on that, I'm hoping for a motherboard between 100-120 USD.

The HDD:
Western Digital Caviar SE16 WD6400AAKS 640GB 7200 RPM 16MB

I'm also thinking of getting Vista and 4 gigs of ram (1066).

There are a few things I'm unsure of. First, are those CPU's going to be a bottleneck for the gpu? If so, what's a good cpu or a decent motherboard that could also a handle maybe an i7 or Phenom II in a year or two? My second concern is if it will fit into that case. And lastly, I am totally clueless when it comes to the power supply. When people start discussing rails and amps I just get lost. I know I have a lot of questions and am probably a little vague, but any suggestions would be greatly appreciated. Thanks.

Are you sure the GTX 280 fits in that case? It's a huge card. I'd suggest a CoolerMaster RC-690 instead.

Good choice of HDD.

MB: GA-EP45-UD3R ($105 at newegg) if you get an Intel CPU.

Yes all three of those CPUs will bottleneck the GTX 280. This article can give you an idea about which CPUs do best.

Here's some good RAM:

Get Vista 64-bit.

PSU:

Thank you for the advice and the guide linked in your sig, very helpful.

I already have:

EVGA GTX 280 1GB SC
Samsung dvd rw drive

I am leaning toward buying these:

CPU: Intel E7300 (OC'ed up around a little more than 3 Ghz probably)
MB: GA-EP45-UD3R
Ram: G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800
OS: Vista 64-bit
Case: Antec 300
PSU: Earthwatts 650w
HDD: Western Digital Caviar SE16 WD6400AAKS 640GB 7200 RPM 16MB

The new parts add up to about 500.00 USD. I don't exactly have money to burn, but does anyone think there are any other parts I could get more bang for the buck? I could expand the budget if it will net me decent gains, although hopefully no more than another 100.00, maybe going for the e8400/q6600? If not, I could always wait another year and put more money into it then. Any ideas or suggestions before I pull the trigger on this? Thanks.

Between E8400 and Q6600, the E8400 will serve you better in games. The Q6600 would do better in FSX and GTA4, but that's about it. OK, to be fair, the Q6600 will do better in any game if you run things in the background while playing.

If you can afford an extra $100, I suggest upgrading to E8500 (an extra $68) and adding a Xigmatek HDT-S1283. Then get that E8500 to 3.6GHz or more. TBH, I don't know if it's worth it. It depends on your games. Maybe the E7300 is enough for what you do.

I probably should have mentioned my use earlier. I really don't do any heavy multitasking. No video encoding or rendering while playing games or whatever else. The most I usually do at once is browse the internet while playing music. Based on what I've read I think the e8400 or e8500 might be my best bet. I would like to play some new games, but I'm not concerned about getting 60fps on very high in crysis. Enough to play Fallout 3 and Empires: Total War when it comes out would make me happy for now. I think I may go for the 8500 and cooler you suggested. I'm thinking it will be worth it when new games come out in a year and after. Thanks again.
