I am using AMD and got a 6 core cpu for 174.99 2.8ghz. It looks like you have to stick with intel or I would suggest getting a six core. It actually has a core booster so currently 3 of my cores are running at 3.3ghz when not using all 6 cores.
I was gonna buy a core i-5 for my server machine but just used my other amd x4 for it. I am not sure if that processor you are looking at is 4 core or 2core with 4 threads, but make sure to get a quad core cpu or switch to amd and get the x6.
That video card is nvidias new mid range card the 550, 560, 570 I am sure it will work fine even at some high settings. I can't recommend any better video card since that one seems good and is something I would get if not the 570 on sale might cost 270-300?
