From my own experience 2 6850's in CF are equal to a Gtx 580, people usually put the 6850/460 1gb in the same range of performance so it should hold true for the 460's.
BUT it comes at a price:
You need to wait when new games are released for the profiles/drivers. Some people also get "stuttering".
I myself have never seen it, but other people seem to.
To me the downsides are negligible in comparison to the savings: You get gtx 580 performance for cheap.
Yes, I agree completely. That is exactly why I decided to buy an SLI (x8/x8) motherboard in the first place. I think it would be a waste not to use the feature. The benefits of having 2 mid-range cards, which parallel the performance of a high-end card, but for a fraction of the cost (I think I'd be saving about $100 since GTX580s can be as low as $330) . http://ncix.ca/products/?sku=67644&vpn=58NLH5DI5TXX&manufacture=Galaxy%20Technology&promoid=1027
Actually, NCIX just had a sale where the EVGA GTX670 FTW was like $340 making ^ not a good deal at all.
Just to re-iterate the cons to SLI which you've already mentioned:
- Power Consumption
- Driver profile updates
- "Micro-stuttering" ... or not.
* Did I miss anything?
Is that worth $100 in savings? I think I can deal with it.
Does anyone know where I can buy GTX460s for even cheaper? ><"
I'd be extremely grateful if someone would help a fellow forum-er!
