To crossfire or wait?

post #1 of 7
Thread Starter 
Hey everyone I have a reference 7970 and I play at 2560x1600, and in some games I would like more gpu power. I run it at 1080mhz and 1500mhz mem at 1.131volts.

I can buy a new 7970 (non ghz) for $330. But I'm really afraid of crossfire, I came from 2x6950s and had a lot of micro stutter, but I hear that 7970s have better cfx support and its better. Also I know cfx doesn't work in windowed modes of games, does NVidias SLI work in windowed mode?

So Im wondering If I should sell my 7970 and get 2x hydro copper 780s (this would be double the cost of CFX and wc), or crossfire and wc both of them ,OR wait and watercool my 7970 and oc it more.

I'd sell the 7970 and get one GTX 780 for now. Get another 780 later if you feel you need more power.

But two 780s at that resolution is the sweet spot.

for high resolution 780 is the way to go. But two 7970 will also do the job , but you will need more power and it adds extra heat. Go for the 780

I seriously would not bother with Amd cfx now. Maybe it will get fixed with the new cfx driver.
I
Got myself a 1440p monitor and a 7970 @ 925mhz and I find it enough. Like MrTooshort said sell your 7970 and get a gtx 780 if you really want something that will give you a better experience. On the other hand that "better experience" can be given by number and Its not that convincing. On bf3 1600p a 7970 oc like yours gould get ~52 fps on ultra. On the same setting a gtx 780 srock gets arroud ~59 fps. So its roughly better but the cost for that 7 fps is arroud 300$. If you sell your 7970 youll get 330 to 350 and your new gtx 780 will cost above 650$.
I homestly would keep your 7970, drop those eye candy to high instead of ultra ( mssa and shadows are fps killer) and wait for a better ratio of improvement.
Otherwise the cfx 7970 give a massive fps increase, but not really a better experience with the current driver.

Unless you are going for a seriously over the top mega-build, never start off with SLI/Crossfire.

If you are a hard core gamer ... Take your absolute maximum budget. Then multiple that by 1.2. Then buy the fastest single GPU you can with that money. Then in about 2 years, buy another card of the same type when everyone else is getting rid of their card for 0.4 to 0.5 times what you paid for yours.

That way you will have a system that is great from day 1, and can be upgraded to a good system 2 years from now, and last you at least for 4 years (if not more).

Starting off with SLI/Crossfire just hoses you, since you never get double the performance with 2 cards, and it will just end up having you take a loss 2 years from now when something causes you to ditch BOTH cards and start over.

I know im late to the party, but i also wouldnt do crossfire.

i got rid of my 2 7870s because the micro stutter was unbearable.

got a single gtx 780 and loving it, tho i can see myself getting another for sli when prices drop a bit.
