6870 or Overclocked 6850?

[BMOSound]

Hi,
I'm looking at buying a new rig and trying to decide if I should get a XFX 6870, or save some dollars and get the ASUS 6850.
The ASUS 6850 is a dual fan design so would it be a good overclocker? If it does would it be as good as the 6870?
Also, is 8GB RAM over the top?


Here's the rest of my rig that I'm looking at:
AMD Phenom X4 955BE (Will be overclocked)
Corsair XMS3 8 GB RAM
Asus M4N68T-M V2 Motherboard
Aywun 550W Power Supply (Already have it)

All the other stuff I've got

If you need any other information just ask

Thanks

For the GPUs, I would grab the hd6870 if you can. The RAM, 8gb is what you want now, 4gb should be minimum. that won't be a good overclocking motherboard. Also, I wouldn't trust that PSU with any overclocking let alone a system with an aftermarket GPU like that. If I were you, I would look into a new motherboard and PSU. The rest looks great. If you couldn't change the motherboard, I would at least look into a new PSU.

Yea, I'll be using 1080p
My current rig is Intel e2180 overclocked to 3.2Ghz and a 9800gtx
Wouldnt my current set up use more power? Not to sure though
I'll also look into a different motherboard. What would you suggest?

Thanks for the quick replies

Would a GIGABYTE GA-M68MT-S2P motherboard be good for overclocking?

your power supply sounds sketch without looking it up....

secondly if everything else is in line id def go for a gtx 560 or 6870 over a 6850

in the end your psu may be fine but if your rig craps out you know the culprit

Ditch that motherboard I just said. Doesn't support ddr3 1333
Does anyone have suggestion for a rig under $400. Just need CPU, RAM, motherboard and graphics card. I know it isn't much of a budget lol

6850 has more overclocking headroom cause it's the same gpu with lower clocks and some stream processor disabled. my sapphire hd 6850 easily passes a 6870 at 850/1171 (i can reach 970mhz but the bottleneck on this card is memory clock).
get a 700w psu so you can add a card latter.

aywun power supplies are cheap rubbish, it will probably blow up. It may be ok with the 6850 if you dont overclock anything. but, if its already running a 9800gtx ok, the 6850 wouldnt use more power than that,. But the phenom x4 will use more power than your core 2.

^yeah that's basically what I was implying; that the psu is crap might as well get a decent psu and a 6870 or something of the likelihood, it will be worth it to save 1 more paycheck in order to make the proper purchase especially if you plan on oc'ing
