Using Tri-SLI 470 GTX, would a 6990 solve my problems?

post #1 of 8
Thread Starter 
As stated, I've got three 470 GTX cards in my system currently. All are waterblocked and working as intended. However, the power draw of my system is borderline ludicrous and the heat generated in my loop is almost too much. I can't overclock these cards too far because I literally trip my breaker.

The issue is, I game at 2560x1600. Is a single 6990 really going to be enough to last me a while at this resolution? AA is necessary for me, usually around 4x. So, the 2gb VRAM is appealing per GPU.

Is it worth it to switch to a 6990? Or should I just wait for new tech around Q4?

it will definitely use way less power that's for sure but performance will be little less than what you have now. but it should be plenty.

Indeed. VRAM with the 470's is another concern, 1280mb seems like nothing with 2560x1600.

yeah but 2GB per GPU should be more than enough

HD6990:http://www.guru3d.com/article/radeon-hd-6990-review/14

As the above data shown, the performance between the 2 stock setups are very similar. Their overclocked status should be also similar.
IMHO, it is not worth the switch (time, money, performance, thermal, noise...considered).

Wait until Q4 for Kepler and HD7xxx series.

Without any AA, a single 6990 will be plenty at 2560X1600.

Unfortunately my eyes are very sensitive to jaggies. Need that AA.

Sorry, I misread.

I can play every games out there with 4AA/8AA with a 6990+6970, even Stalker COP, Crysis and Metro 2033. But only one 6990, not so sure. Maybe 4AA everywhere?

But you will now have alot more VRAM with a 6990. That makes a major difference with AA.
