570 or 6950?

post #1 of 104

6950 - http://www.newegg.com/Product/Produc...82E16814102945

I will NOT be playing BF3. Could someone also please explain to me the price difference and the memory difference. When does more memory come into play?
I will be running 2 monitors but I would only be gaming on one of them.

Memory higher than 1-1.25GB comes into play only if you game on a really huge resolution (multiple monitor setups).

GTX 570 is faster than HD 6970, which is obviously faster than HD 6950 (although this particular card is apparently unlock-able to 6970).

Assuming that 6950 really unlocks into 6970 (I'm fairly certain it does but please correct if I'm wrong) then I'd definitely take it over GTX 570, the difference in speed isn't worth $100.

Well I'd like to note that I recorded using 1.2GB of memory running Crysis 1 on full settings at 1920x1080 so don't be so sure 1.2GB is going to be ok for just one monitor in the future.

The 570 is the faster card, but the lack of memory might be a wall for you in the near future. If you have money for a 570 why not get a 6970 with a good cooler on it and OC it a bit. That way you get great performance and have the memory you may very well need in the future.

Also the Dirt 3 6950 has a high success rate of unlocking to a 6970 and also if it does not you can just run Trixx and load the card @ 1.5v 880/1350 and get 6970 performance for a whole deal less than the 570 will cost you plus the 2GB of RAM. I know this because I have 2 friends running those cards in computers which I built and both of them overclocked to those settings like a charm without any effort what so ever.

Personally, I wouldn't get either. The 6950 is non-ref so expect lower card quality and higher unlocking risk, where the 570 is pre-OC'ed (no use) with weak VRM's.

You can get the XFX reference 6970 with 2GB vRAM, Digital PWM, real-time support and such.

I recall a review showing nearly zero benefit of having more than 1GB of VRAM on a single monitor resolutions, let me find the link.

By the time the memory will become a problem, 570 will be probably too slow to max out modern games anyway.

I'd like to second this post.

Also I remember reading about lots of 570s getting killed with very weak overclocks because of the crappy VRMs on them. If you aren't going to OC at all and you aren't worried about future memory issues the 570 is the faster card though I would most definitely go 6970.

+ OC = HD 6970 in some games
and get a better CPU cooler with those 100$ that you save
post #9 of 104
OP, I just got the Sapphire HD 6950 you listed. It is a fantastic card. I actually sold my GTX 580 that was a good overclocker because I like the 6950 so much for the money. Plus after selling the free games (Deus Ex and Dirt 3) I got it for under $200 once rebate is factored in.

1) Mine came already unlocked, just moved the switch, BAM 6970 shaders!
2) At a modest 1.18v, mine OC's to 970/1370 stable and artifact free
3) Runs cool and quiet, 37C idle and 60C load with BF3 after about 30 minutes

I'd suggest the TOXIC if you're going HD-6950, though the DIRT3 edition is a pretty good card as well.

Both of these Sapphire Cards have pretty decent potential to UNLOCK to HD-6970's ... the TOXIC @ 66-75% success rate, the DIRT3 @ 33-50% success rate. And BOTH are DUAL BIOS cards, meaning there are TWO BIOS' on the card and you can flip a switch to go back and forth between them. The 1st BIOS is the FACTORY DEFAULT and Safety Net if you will, the 2nd BIOS has the Unlocked Shaders /6970 profile on it so with the flip of a simple switch you get a 3-5% performance boost. BOTH cards also OVERCLOCK very well, the DIRT3 comes w/ a standard 6950 profile 800/1250, while the TOXIC comes FACTORY OC'd at 880/1300 making it 99% of the way a 6970 out of the box if it successfully unlocks, and both cards can OC near or past the 1000 MHz mark giving them performance levels that match or surpass a stock GTX-570 and can often butt heads against a stock GTX-580 card. In fact one of the reviews had such a TOXIC beating a stock GTX-580 in 2 of 3 performance benchmarks they ran.

Now consider you get all that at about $70 to $120 less than the cheapest GTX-570's. And as has been mentioned, YES there have been reports of several GTX-570 frying due to OC's that overheat the VRAMs.

The other Card I'd suggest is the MSI PE/OC TwinFrozrIII 2GB HD-6950. Also a Great Card and in between the TOXIC and DIRT3 edition as far as successful unlock rates. I wouldn't recommend that 1GB version unless your budget required it, but if you're looking at a GTX-570 also I'm guessing that's not the case.
