Neospiral :
According to the benchmarks I've seen, the HD 4600 integrated graphics will probably outperform your old video card. For your uses, you want a serious amount of RAM. What are you running with?
The RAM is the last thing left to buy for this build (unless I decide to get a new video card), and I'm just waiting on a good deal for 16GB of 1600mHz DDR3 (if anyone has any recommendations, I'd appreciate it).
I'm mainly wondering if it's worth keeping the old video card (and maybe doubling it up with another video card using crossfire?) to keep from taxing the CPU by having to use the integrated graphics.
