I've gone through several benchmarks, read an article (8 months old) on micro-stuttering with Crossfire/SLI, seen plenty of YT demonstration videos, and surfed for countless hours on Amazon.
Some setups I've had in mind are as follows:
(first one is listed on my specs as I'm a couple of days from ordering the parts, so I have some time to change my mind)
ASUS GTX 560Ti TOP 1GB DDR5 - 2-way SLI (£352)
This has some major power, and you can understand why I was going to (and may still) go for this powerful setup, easily rivaling a single GTX 580 GPU, in regards to performance. My concern is micro-stuttering, naturally, but I can't find any info or comments from people who have or haven't experience considerable micro-stuttering issues with these two cards in SLI.
MSI Twin Frozr II GTX 560Ti OC 1GB - 2-way SLI (£344)
This was my original temptation, but it looks like these cards push out a lot of heat within the case, and although I have a very well air cooled case, I don't have a desire to stink up my case with these two cookers. The performance, however, would probably match or surpass that of the ASUS alternative, so I'm thinking ASUS for a better cooling solution, and I'm seeing a lot of reviews claiming the ASUS cards to be of high quality, which is always nice to know!
EVGA/Zotac GTX 580 1.5GB (£300-£400)
EVGA Nvidia GTX580 1536MB 384-Bit GDDR5 Graphics Card: Amazon.co.uk: Computers & Accessories
I've only properly considered this today, after reading the article on micro-stuttering, as this card seems to be a very
powerful card, without the worry of micro-stutter, and maybe some day I could add a 2nd. This seems to be a sensible choice and I imagine I'll get a few posters saying to go for this option, but my concern with this (aside from never being met with an 8-pin GPU power connector) is losing out on any bonuses that come with SLI (such as AA enhancements, or is this AMD only?) as well as heat/power. I'll be ordering a TX750 or TX850 enthusiast edition Corsair PSU, depending which is best to go for; 750w is £80 and the 850w is £90.
I have the funds, but I'd ideally like to avoid spending cash that really
isn't needed; I want the best I can get.
I have a feeling some of you might ask:
"What will you be using the GPU(s) for?"
- Primarily gaming; I don't deal with 3D modeling and the like.
"What's your budget?"
- Probably £400 for the GPU(s) alone.
"Are you more concerned about now, or the future?"
- Probably the future, as I don't want to be shelling out in a year's time or something; the above options appear to last me for several years while still retaining decent performance, especially the SLI setups, as hopefully they'll improve or eradicate the micro-stutter issue.
This will be my last big upgrade for at least a year, because I've already spent heaps and it's pretty much all built up, now.
