OVERCLOCKING: Yes slighty
MONITOR RESOLUTION: 1920x1080 ADDITIONAL COMMENTS: I dont need to play games on super duper pooper high settings, so 58xx series wasnt worth it at the moment, but maybe a future upgrade.
I would get a newer motherboard that at least has USB3.
The 750W PSU is too big for a 5770. You could easily drop to a nice Antec Neo Eco 520 or Earthwatts 640 or a Corsair 550.
The WD "FALS" is a slow, old hard drive model. It will be substantially slower than the WD "FAEX" model or a Samsung F3 or Seagate 7200.12 1TB HDD. The Samsung and Seagate are also cheaper.
The arctic cooler freeser is only a 92mm cooler. You will get better cooling quieter with a 120mm cooler like the Coolemaster Hyper 212, Scythe Mugen 2, Sunbeam Core contact freezer or any Xigmatec 1283 series cooler. I think the hyper 212 is cheaper on amazon.com right now.
A 640 GB hdd will have two 320GB platters and will not be as fast as the 500GB platter drives.
The cooler is more of a noise than cooling issue. A larger fan will cool the same amount at a slower RPM generating more noise. Not a big deal as the arctic cooler and coolermaster tx3 ar both good 92mm coolers that will do much better than the stock cooler.
i would also go for a seagate 1 TB hard drive...i have a 640 black right now and i'm running out of space pretty quick...games nowadays are not that small and i'm sure you download things to watch too and keepign them...
PSU wise the antec earthwatt 650w would be a good choice which gives you the option to get another 5770 later for crossfire.
