First time build - "budget gaming" PC ~$800

APPROXIMATE PURCHASE DATE: Next two weeks

BUDGET RANGE: ~$800 (excluding peripherals/accessories/monitor)

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: gaming, surfing the internet, watching movies

PARTS NOT REQUIRED: speakers, monitor

PREFERRED WEBSITE(S) FOR PARTS: any US based site, also have a Microcenter fairly convenient (Boston)

PARTS PREFERENCES: Want good value in system that I won't need to upgrade really (at least not totally overhaul, maybe put in a better graphics card or OC the CPU) for a few years - won't be playing the latest games on it, maybe Starcraft 2 might be the only thing I really play

OVERCLOCKING: Probably not [ b]SLI OR CROSSFIRE[/b]: No

MONITOR RESOLUTION: Just purchased 24" Dell monitor - 1900x1200

ADDITIONAL COMMENTS: Have a wireless mouse but will be on the lookout for any sweet wireless keyboard or combo wireless mouse/keyboards deals in next couple of weeks

Here is what I am thinking for parts:

Total is ~$800 before tax, shipping, and rebates

Some questions I have are:
1) Overall, is this a good value build? Can I get more "bang for the buck" by using a more limited processor or GPU?
2) Do I have too much power supply?
3) Is the MB/CPU combo any good? Could I do better with a better MB but weaker CPU such as http://www.newegg.com/Product/Comb [...] mbo.205337
(supporting DDR3 memory - would save me having to buy new memory whenever I upgrade)
4) Do I need a cooler? I may want to do some limited overclocking. The CPU comes with a stock cooler, right?
5) This is my first time building - what else do I need? Any particular screwdriver recommendations? Do I need one of those antistatic wrist bands? What about thermal paste or does that come with the stock cooler?
6) I'll be able to keep using this copy of Windows Vista OEM, even if I do a major upgrade to the computer e.g. change the MB and CPU a few years from now? Assuming the Windows 7 upgrade comes as a CD so that will still work...

Id go with a 5770 over at 4870 personally. you get dx11, lower power consumption, and eyefinity for very similar performance

lol nope, i had no clue! lol should prolly pay more attention to that lol
