here are a few items you might think about. I have the board. I use the ram ( not ddr3 ) in several machines...... video card should do really good at your res. it's under your budget so you can make "upgrades" if you want...... $416.00......... if you don't have windows 7 64bit OEM........ look for it. was $80 yesterday I think. be a good item to add to this build. I have to add.... this build will obliterate what you have now.
I went over budget a little but only because I added a few items you can remove, like ram, a power supply and CPU heatsink. For $50 over budget though I think these would be a smart investment. I'm sure you are aware this will not get you a top of the line gaming machine, but it will be good enough for playing CODMW3, BF3, Diablo 3 or GTA IV.
Check out the June System Builder's $500 gaming PC. You'll see they used less ram but it is 1333 and I'm guessing the ram you have isn't. Could be wrong. The only thing better on their build is they are up one step on the GPU and maybe that is something you should consider doing. If their $500 build says anything it is that you should invest heavily in the GPU, in this case roughly 45%.
There is obviously a million ways to do this depending on how perferct you want the setting to be while playing but in reality, I'm guessing you would be more than happy with this machine. I tried to balance performance with user reviews on newegg, keeping everything about 4 eggs.
The benchmarks for Tomshardware's $500 machine puts BF3 at 70.8 Frames per second on ultra with 1280x720 resolution. Good enough for me.

Based on this information you may consider looking at the 480, even though it is two years old it looks like it still out benches some of the newer cards and still cost less. One this to consider is that the 480 has a recommended power supply of 600w or more.
okay, not the greatest. but having said that. the stuff I posted will probably use less power than your old stuff and you may be able to get away with using your old one. I will however look and see if I can add a decent but inexpensive one to the build and stay withing you budget. give me a little bit and I'll amend this post..........
here are a few different ones. hard to pick for me because I usually buy bigger PSu's.. I figured these were probably the better of the inexpensive ones without compromising too much..... read them over and you either select one or you don't. The smallest one, the 380, I would pass on. not really enough juice for me but I have 3 of them and have had zero problems... but please look at the others. Little more juice..... amps.
............. 3 of links didn't work for me.......
I don't see memory listed now.... ???
I would drop the cooler. you probably won't need it.
picked the "second" best PS. that's okay. but hoped you would have went for the more expensive one. More PCI-E connectors.......... if you ever decide to upgrade to a bigger card or carry this PS over to another machine in the future if it still works.................. just something to think about.
yes, what I can see is okay........ don't forget the ram............ if it's not listed
