I don't plan on overclocking this, since it's already 3.1 ghz, which is fast, but for the sake of future games requiring faster cpu speeds, i read this is a great overclocker and has a possibility to unlock 4 cores. I'd probably buy an additional heatsink/fan if I do overclock it, but that won't be til a few years down the road, if I do at all, I read it's not good for the processor.

It's a combo deal that gives windows vista home premium 64-bit and a case that comes with power supply. Is 500w enough for this computer?

Does this look good? If you have any suggestions, show me a link at newegg.com please. Thanks...Oh and this isn't suppose to be a dominant gaming PC, just a fairly good one. Total comes to just under $700, so if you make a sugestion, keep it in that range.

Your RAM is CL 9. You can get CL 7:

You really can't use a Raidmax PSU. You can get an education about PSUs in my guide at the top of the forum if you like.

You can match the performance of that video card for less though:

Get a 4850. Wont affect the performance and is cheaper than 9800 GTX+.
With the money saved, get a 550 W power supply MINIMUM from Corsair, PC P&C, Antec, Seasonic, OCZ etc.
If you decide to go for cooler master though, make sure you get real power. Avoid Extremem power at all costs as it is known to bring several systems down and is VERY unreliable.

I would highly recommend this:

Its modular, and ample for your needs...

Good luck gaming.
