New build advice for $750-800 gaming pc

Hi,
Looking to buy parts for a gaming PC next couple days, replacing old computer which is slow

Approximate Purchase Date: Preferably Friday, Saturday (10/5-10/6)

Budget Range: around $750-800 with rebates/shipping/etc

System Usage from Most to Least Important: gaming (stuff like skyrim, WOW, FPS)

Are you buying a monitor: No

Do you need to buy OS: No

Preferred Website(s) for Parts: newegg

Location: Fairfax, VA. I live near a microcenter

Overclocking: maybe

SLI or Crossfire: maybe


My considerations so far:

I live near a microcenter and looks like their cpu/mobo deal is best.

CPU: i5-3570K $190

Motherboard: Asus P8Z77-V LX Socket 1155 Z77 ATX Intel Motherboard $70 (with cpu)

Graphics: XFX Double D FX-795A-TDJC Radeon HD 7950 3GB $270 (after rebate)

RAM: CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) $38 (with promo code)

SAMSUNG DVD Burner

No shipping

comes out to be about $745 (does not include taxes from microcenter purchase).

What do you guys think?


Some questions/alternatives:

1) aftermarket cooling necessary? my PSU ok?

Newegg currently has sale on for $213 after rebates and promo code:
XFX Double D Radeon HD 7870 GHz Edition Black Edition 2GB GDDR5 HDCP Ready CrossFireX Support Video Card

2) Is the 7950 worth $57 more than the 7870? perhaps I'm better off spending elsewhere like on a SSD?

3) Also, microcenter has alternative motherboards on sale which can combo with the cpu, dunno if I'm better off spending a bit more on that.

  1. this seems like a great build and yes after market cooling is required since you do have a k version cpu you can grab the cm hyper 212 for like 20 bucks and i would personally get the 7950 but the 7870 is still a great card if you want to grab that instead and i would recomend getting a higher wattage cpu maybe 700w if you plan to crossfire two 7950 or two 7870 in the future
  2. Well that mobo can't sli or cfx.
    This one can though

    If you are going to cfx, you might want to consider a 700w psu. But you would probably do fine with that 600w

    For the 7870 vs 7950. here are some benchmarks
    http://www.anandtech.com/bench/Product/548?vs=550
    As you can see they aren't substantially higher, but I think the 7950 will be better in the future because of higher bus (256 vs 384) and more ram.
  3. I was considering it but, on second thought, I dont think I'll do any cfx. Probably stick with the current mobo and psu. Thanks for input.
  4. Don't get the OCZ ModXStream PSU. It's not that great and it has bad amperage on the +12v rail for a 600w.
  5. Well I would still get that msi motherboard because it is still cheaper, and it leaves the option for cfx if you so please. Spending less got higher quality sounds like a good deal to me.
