Here is my specs, I don't know exactly what to put, but here:
Intel Core i5 650 @ 3.20GHz
8.00 GB Dual-Channel DDR3 @ 531MHz
Dell Inc. 0T568R (CPU 1)
1024MB GeForce GT 220 (nVidia)
932GB Western Digital WDC WD1001FAES-75W7A0 (RAID)
This is just copied and pasted from Speccy. If you need more info tell me and I'll try to find it. I don't know much about building computers, but I pretty much just want a new video card and a power supply to go along with it(I was recommended a 750w psu, but I don't know what to get beyond that, brands, sizes, etc.).
I've searched everywhere for these answers and I just can't find a clear one. At least not for someone like me who doesn't know anything about building a computer. How do I know what will fit my computer? I noticed my psu fit perfectly in the shelf at the top of my case and anything bigger would be too big, are all modern psus the same size or am I going to have to measure it?
It's for gaming. And I'd like a video card that could play a game like GTA4 or Battlefield with no lag. I will spend up to $450 for a graphics card and power supply, assuming that is all I need.
