And which 350W PSU do you have ? If it is of decent quality, then you can check out even the HD 4770...
I don't believe the video card is sufficent, i would get a cheaper brand of memory , even something that won't overclock in order to have more to spend on the video card. Your monitors resolution is high and you'll need something powerful to play games at high speed. a 10% speed increase from overclocking expensive memory isn't worth it. A better card will get you alot more.
I am leaning towards this setup now, although a little less $$ would be great, this build will need to last for some time to come. I opted for a new case, so I can keep my current rig up and running in case of issues.
**I am going to partition the new HDD and install XP on one(20gb). I have most of my programs currently on 2 other drives. Can I reuse these old drives(No Boot partitions) without reinstalling ALL of my programs? What is the best way to do so?
That's a good choice, the video card is good with low ram but according to a recent article on tomshardware it isn't as important as once thought.
A 4670 is not for gaming, more for an HTPC setup. You need at least a single 4850. Also, no need for DDR3 if you don't need it. Still, in Canada, the difference between DDR2 and DDR3 is about 20$ on most 1333 MHz ram.
Sincerely, you need to invest a little more to get a decent gaming PC. What you can do is buying a AM3 system with an IGP (Integrated Graphic Processor) on the motherboard and buy the graphic card for your gaming purpose later.
^ The 5770 is stronger than the HD 4850...they loose to the 4870...I think you are talking about the 5750...And also in that case, the 4850 and the 5750 are pretty evenly matched...But as the 5750s are scarcely available, its hard to find them at a good price...So I would suggest you buy the graphics card last...By then the availablity might improve...But do check everyday for any deals...
^ These are the latest version of that RAM sets that you had listed...And they have the same timings, speed and voltage and cost $2 less...And the ones that you had listed dont have Free shipping but these have...
