This is my first attempt at building a completely from scratch
Hopefully it's better than the stock 3000 h210 lenovo pc I've been using for a while
Case: Mid tower case that comes with 1 fan wondering if I need to add more
DvD drive: Sony AD-7280S-0B 24x SATA
Hard drive: 500 GB SATA III
Motherboard: GA-880GM-D2H AM3 motherboard
Processor: AMD Phenom II X4 965 AM3 3.4Ghz
RAM: 2x4gb ddr3
Video card: nvidia 460gtx v2 (already have)
PSU: Cooler master 550W (already have)
I already upgraded the base psu and gfx card so it can actually do 3D stuff without being super laggy. Now that I have more to spend, I'm looking to upgrade into ddr3 and quad core. My biggest concern is whether or not everything will work together and be good buddy or some of it won't be nice and have problems. Also wondering if it will be a big gain or not even noticable. I'll be using window 7 pro 64-bit OS. If I'm missing some vital component please let me know.
update: current cost about $400 (since I already have the gfx and psu), if some of it can be replace by much better part for a small extra price that's nice too wiling to go up to $500.
