Building a new system, HD 7970 or GTX 680?

post #1 of 24
Thread Starter 
Hiya, after a few years of never having an, "upscale," computer, I finally decided to build one. But, Im up in the air between the GTX 680 and HD 7970 Non-GHz Edition. I've been watching numerous benchmark tests and still can't decide. Does anyone have input? PhysX isn't such a major concern for me, but, I'm also getting the AMD FX-8350, since my budget isn't large enough for an i7-3770K. Would an AMD processor prefer and AMD card? But at the moment, Im going for the GTX 680. (I know an OC 670 would perform just as well, but I'm just going to stick with the 680 or 7970.)

Get the 7970 (or Ghz if you can find it for a good price) and OC it, 7970 is cheaper(since you seem to be budget constraint), faster at max OC, with wider VRM bus(384 bit) and more Vram(3GB)

If there was a single 7970 model I liked & not out of stock, I wouldn't be on this 680 Lightning now.

Honestly and this is just my opinion but i can't stomach the poor single threaded performance of the bulldozer architecture. I do think you could get away with 300$ for i5-3570k/mobo combo, maybe a little over. Just throwing that out there.

As for the card i really like the 7970 drivers keep improving performance and if you manage to get a good overclocker bump it to ghz speeds or higher and you have much more value per $. That being said i have no idea which ones are voltage locked or not and it seems to me (others will disagree) that the 7970 QC is just all over the place. I had to RMA mine which it's XFX so that could've been the problem from the get go. I've never had to RMA anything before up until now, i guess it's part of the business though. Despite all my worries and concerns i still say 7970 just because at stock it's a good niche above the 670 and trades blows with the 680, and clocked up a minor 75mhz it's ahead of the 680 roughly.

Oh here is a 7970ghz edition (Gigabyte) for 430$ seemed like a pretty cheap price considering it's Ghz edition. Stock clock is supposedly 1100mhz according to newegg which would be stellar performance for the money.

Get a 7970 GHz Edition and call it a day. The 680 has nothing on that card. biggrin.gif

Alright, all 3 who have posted so far seem to be on the side of the 7970, so that brings me to 2 more questions:
1.) What's the best software to OC a 7970?
2.) What would be the best brand? (Gigabyte, MSI, Diamond, etc.)
post #6 of 24
I can't answer on the best brand as i'm honestly not sure. I do see Sapphire, MSI, Gigabyte, and Asus recommended pretty often. I like MSI afterburner personally but i know a lot of people like TriXX and some use the Catalyst control center to overclock.

670 SLI if you can find it at a good price smile.gif

Heres a thread I just made (NCIX deal Galaxy 670 at 309$)

I have this (http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1817062&csid=_61) and love it. It also has a lifetime warranty. Right now it is overclocked to 1200mhz core and 1600 ram with 1200vddc This is just my test/benching speed. Temps get a little high for my liking at this speed in game for a long time (stock cooler). I am using the Sapphire TriXX software. I also have the FX8530 and love it...it was a huge step up from my FX8120...sure it's not quite as fast as the i7s but running at 4.96ghz isn't bad on all 8 cores...even at stock speed it played my games well I personally think it is a great budget CPU.

1 - Trixx for benching, afterburner 24-7

2 - reference baby, screw the wannabe customs, get a diamond 7970 non ghz.


If I was going 680, I would get a lightning 680 or bust.
