Also, any parts that are good replacements for anything I have?Is this a good build?
Yes, the 5850 is a much better video card. I would advise against the iffy brand Ultra PSU though

Here's a suggestion for a better performing build around the same price though

Core i5 2500K CPU - $220
ASRock P67 4 Extreme motherboard - $155
RAM - Same, although you really only need 4 GB for gaming, but might as well get 8 GB since it's cheap now - $75
Sound card - Modern motherboards have decent quality audio. You don't need one unless you have a high end speaker system to plug your PC into
Case, DVD, Monitor - Good
Video card -Take the cash left over from the motherboard and get a Nvidia 560 GTX. Better than the 5850
Power supply. Antec or Corsair 80+ high efficiency PSU 650 watts

Hard drive. I'd definitely go Western Digital Caviar Black with 32 or 64mb cache instead of the 16mb on the Seagate

My system will play anything on 1920 x 1080 very well, and it's similar to the one I listed
Mine is

Core i7 2600K OC to 4.4 ghz
8 GB DDR3 1600mhz GSkill Ripjaw RAM
WD Caviar Black 1.5 TB 64 mb cache 7200 rpm HDD
Nvidia PNY 570 GTX video card
ASRock 67 4 extreme motherboard. Great board for the price!
NZXT Tempest EVO case
Win 7 x64 bit
LG Glossy no-glare 23" LCD 1920 x 1080 monitor
Sunbeam 780 watt PSU (crappy low efficiency PSU that barely gets me by)
CoolerMaster Hyper 212+ air cooler - $30, soon to be replaced with a Noctua
