I'm looking into buying a new computer for gaming and general use. My current PC is acceptable for gaming, but it was essentially an entry-level rig, and I like to think I can pick parts a little better than I could when I built that one. I've refined the parts list for my new computer quite a bit on my own, and would appreciate the input of those with more experience than myself.
Case: Cooler Master Storm Series Trooper for $150
Mobo: ASUS Sabertooth Z77 LGA 1155 for $240
CPU: Intel Core i7 2700k (planning on oc'ing) for $350
RAM: 2x 8GB DDR3 1866 G.Skill Sniper for $80
GPU: EVGA GeForce GTX 670 2GB for $410
Drives: Kingston HyperX 120GB boot drive for $100; WD Black 2TB 7200rpm storage drive for $150
CPU Cooler: Zalman CNPS9900MAX-R for $75 w/ Arctic Silver 5 for $10
PSU: Cooler Master Silent Pro 80 Plus Bronze Modular for $140
I have gone through the list of items you have picked out and it looks like a nice build to me. The only thing I could find was the cas latency of your RAM was a little high so I looked and found this Kingston RAM which I use myself and have had nothing but success with.This is Kingston Hyper X RAM that is less expensive and has a cas latency of 9. Only thing different is the voltage is 1.65 so you might want to check that out first.
Other than that I would be happy to have that system in my house. Don’t forget to order your operating system too. Easy to forget when looking for hardware. As always this is just my opinion and there are many more people here with lots of expertise that I am sure will be willing to throw their hats into the ring and give their 2 cents worth. Good luck with your build, and have fun getting her up and running.
CPU: I'd personally go for Ivy Bridge, because of the PCI-E 3.0 support. I know current GFX cards can't fully saturate it yet, but other cards probably could(i.e. SATA 3 ports) and for future proofing.
GFX Card: I prefer the 7950, 7970 if you can find one on sale. Much more bang for buck IMO, especially if your doing BitCoin Mining or Handbrake. If you need to utilize Cuda Cores, then the 670 is okay.
PSU: How many watts is it?
CPU Cooler: Have you looked at the Corsair H100? I think it's better IMO.
Case: Search around, you may find a better price. If you don't really need that much space, you can get a normal ATX case for cheaper and invest the money on the GFX.
Drives: Again, look around. I remember seeing a SATA3 240GB SSD for only a little more, and a 3TB SATA3 HDD for around the same price.
Mobo: Good choice! That is all.
Ram: ^
Optical: Nothing to say.
These are the parts I'd get if I had your budget, but remember, this is my only my opinion. Your choices are already good. If you need/ want more help, post your budget so we can help you better.
