|I was wondering if any EG users use Crossfire or SLI and, if so, what are your opinions on it? Also, can two middling cards ever match a high end single card for performance? I don't really know what is considered high end right now but I currently have a GTX 470. Wondering if it's worth going SLI or just going for a straight upgrade to a better single card.|
SLI/Crossfire compared to single-card setups

Noisy, hot, micro-stutters, erratic compatibility and not much of a performance increase for a fair few games.
You are always better off selling your current card and getting a better single card.
Everything thats been said above really. Not surprising really if you consider how many games support quad core processors. SLI is even further down a developers priorities.
I was building a machine today in fact with an ASUS 2011 socket board that supported 4x Crossfire/SLI, and it proudly boasted that with 4 cards you could expect up to 30% more performance(!)
'Bang for your buck' indeed.

I read a lot about microstuttering issues previously and its always put me off. don't have any first hand advice though.

#If its just for gaming then buy responsibly. alot of games will run full throttle on 1-2Gb Vram system. We are seeing games reach the 2Gb+.
If you can afford/justify spending $500US minimum for a top of range card then go for it. It will perform amazingly on benchmarks over "most" crossfire setups depending on choice...then buy another of the same model at much more reasonable price later on if desired to juice up.
What xfire needs to perform best is a quality front end, and quality cards. Microshuttering is not noticable supposedly in most cases...?

its not the ultimate of everything. ive seen high-end games like metro 2033 and skyrim perform without flaw with maximum settings. play it on one card it chokes at high end. put in a pricey $700 card, back to maximum settings.
I paid alot less than 500USD for the two GPU. Giving me 4Gb Vram. 3D capability. More money to spend on other value for money components.
I will one day buy a top range single card. but this setup will suffice for some time. I am waiting for HDMI to get dumped personally. DisplayPort is the future. Will wait for tv/projectors units to catch up.
Most high end graphics will have a DisplayPort/HDMI atm. Also the ULTRA HD comes out at end of year.
this is my opinion based on researching my build for a about a month. built for gaming + 3D + video processing.

I would always go with a single card if it's affordable. However getting a second card to add in rather than buying a new expensive card might work out cheaper for an upgrade of an existing system.

I've got a gtx 480 in SLI with a 3D Blaster VooDoo2 and I'm running GTA at 1000fps.
That's interesting. I have 3000 TNT2's hooked up in a mile long sli chain that gives me 61fps in Crysis 2.
I SLI really that bad? I currently have a GTX580, been an excellent purchase (restored my faith in NVIDIA after a couple of bad experiences) and I've zero need to upgrade any time soon, but I did wonder about shoving another one in 12 months or so down the line when they can probably be had for peanuts.

Micro Stuttering would drive me up the wall, just as bad as a poor framerate so no point really imo.
I can sort of understand lengthening the life of a mid range card, but then surely it would cost more initially to create a PC that could take another card.
But for high end, considering you get people being called idiot for buying the most powerful single card solution as being overkill, the idea that there is people out there prepared to buy two or three baffles me.
My only semi regret is buying a 2560x1440 monitor. As good as it is, and the 580 still pretty much nails everything at max detail/60fps, I know if I'd gone for a smaller 24" 1920x1200/1080 monitor I could probably go a fair bit longer without ever having to reduce settings. Going non-native res is not an option for me, I'd rather have less detail and maintain 60fps.
That's a crazy resolution. At least you know games will run well for at least another year until they release the next gen consoles and raise the baseline specs.

When the 360 was released where did it rate against PCs of the time? Top end?
Pretty good, I remember Call of Duty 2 was state of the art in terms of gaming, and it ran that butter smooth.

Think the 360 was low to midrange but consoles are closed systems you get more bang for your buck.
I love pc gaming, but it's hard to argue that a 7 year old console that still runs reasonably impressive games hasn't delivered.
Saying that, I'm on my 3rd 360 (6th if you include warranty replacements) so, err, maybe not!
