The 7970 is a more powerful card. Unless your use physx pr CUDA or you're a nvidia fanboy the 7970 is a clear winner. :) Linus has a series of test against 670s and 680s and 7970's and 7950's, just go find them ;)

Yeah.. Now I have to decide what manufacturer to choose. Anyone know who would be the best for maximum overclock? I see Sapphire' date=' MSI, and Gigabyte so far (looking on Amazon).[/quote']well The Best card would be the card with the best vrm, the best gpu(luck) and the best cooler. I know off the top of my head that the more expensive twin frozr's and the sapphire dual x are good. You should really check out comparisons. I believe Linus has unboxings and overviews and such of some of the cards.

actually ddr5 has higher latency's

Personally If I'm dropping 1k on a gpu I would want at least a 5 year warranty. Now I've heard varying opinions on pailt. I believe most of the titans are all reference (correct me if I'm wrong), except for the newly announced windforce cooler for the Titan. SO really It comes down to your personal choice of company, the warranties and accessories.

I would also have my vote for the 7950. There is a new 7950 made by sapphire it looks like a reference design 7970!( there is no reference design for the 7950!) Also remember that prices vary widely for these cards. I've seen the 660 ti anywhere between 260-350 bucks.

The max temperature for graphics cards are very high. In the fermi days they were rated up until 105c ( now kepler is rated at 97c as the max temp!). Now with kepler it does start to slow down a bit at 70c. So really as long as you temps aren't exceeding 70c you ca get the sweet boost clock. Now if your temps are regularly hitting like the 80s and 90s I would rma and such. Here is the specification sheet for you gtx 660 [url=http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-660/specifications]http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-660/specifications[/url=http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-660/specifications]

You could get a second 560 ti 448, but the major problem would be power. Now you may have a 650 watt power supply, but that doesn't mean you can just just all 650 watts. Using all 650 watts is not only dangerous in some cases ( with cheaper power supplies) but also inefficient. Ideally you would want at least an 800 watt BRONZE or better rated power supply for a 560 ti 448 core build. In my opinion I would go the route of waiting, or if you really need more power just sell your current card and get a better card. I would recommend a nice 7950 or maybe 670 as an acceptable upgrade, Anything less the a 7950's performance really wouldn't be worth it imo. EDIT: I just read you cpu setup, and I may as well touch on the points of bandwidth constraints and such on motherboards. Currently the 1155( and several other like am3 and such) socket only has 16 lanes of pci-e, Now this is fine if you were running one card. Now lets throw 2/3/4 into the mix. It'll be split into 8x/8x and so on and so fourth. Now this is not really a problem if you have lower end cards that don't need a ton of bandwidth to perform at they're best. With higher end cards There is a bottleneck. This bottleneck not only is from bandwidth constraints of only one 16x lane, but also latency. This really isn't touched on much but it is worth noting that generally speaking the more pci-e lanes available to you ( as in the 2011 socket, or 1366 socket) you get better latency's(latencies?) and also more bandwidth.
