Plus it seems that Crossfire and SLI are having more issues these days. You think it would be getting almost main stream, but it seems like there are more troubles today then there was a year ago.
If I was to buy a single GPU to play 1080P...I think i'd go with a 6970...or a GTX 580. A 6950 or 570/560ti might do the job too. You'll be fine as long as you don't want to max out Metro 2033

Well I would want to max out metro 2033 and also at the same time future proof my system

hurrr.... what PSU do you have i see 850 but what brand and how much power you have on the +12V rail? also a PHII x4 will be a bit of a bottleneck... overclocked or not, you could probably grab a PHII X6 for cheap somewhere and throw it on and OC it to 4GHz

pretty much any CPU temp monitoring software will be compatible. I personally use some windows 7 gadgets for such things, but there are all sorts of monitoring software out there...just try some out and should find one that you like. The only difference is the display. Unless you dig up something that is really old, but that would be hard to do by accident.

Note that your CPU would probably have more troubles with 5850 crossfire than it would with just a single 6950. The crossfire takes some horse power to pull off.

Core temp will monitor your cpu temps very well. also if you are looking for a single card right now i would go with a card with more v-ram, future proof is the key!

that would be an amazing upgrade for you down the road pick up another one... also i may be wrong but i think these cards can be unlocked

Your UD3 board can do Trifire, albiet with limited bandwidth. and the performance increase really isn't worth the trade off of heat and power consumption. If your PSU is a quality unit it will be able to handle Tri-fire no problem, but In my honest opinion being a former 5850 crossfire owner you'll see much better performance in purchasing a 6950 or if you can find it a reference 6950 and flashing the bios.

The third card will only adds something between 25%-35% overall performance. Trifire scaling on 5000 serie is kinda bad.
With only 1Gb of Vram, this setup will be extremely limited by this, not by the GPUs power. So even if you cards can handle more, you won't be able to max everything as now most game require more than 1Gb Vram everything maxed.

So really, I would just stick with a single 5850 overclock it as much as you can. Hell, I am still able to max most of the game I play with my 5870! I will wait one more year or so, when the price of the current gen (7000 & GTX600) will drop, then I will probably buy a new card.

If you want to play Metro2033 *maxed* just disable Advanced DOF. I find this feature interesting but quite useless, it is just a FPS eater... The difference is quite minimal and isn't worth the huge amount of FPS you lose!

I would have to agree with this. At this point and time it wouldn't be worth it getting one or two extra cards as you are still limited by VRAM. I to have thought about adding another 5850 but there isn't anything I play that needs it, other than GTA4 which loves VRAM and BF3 which I don't care for but I know it uses a lot of VRAM. I myself am going to hold off and wait and see how the midrange 7k series fares before considering upgrading.

I have to agree with this as well, there aren't any games out I can't max apart from the ones that require more VRAM.

I'd do a simple CrossfireX (2x 5850) and with the difference upgrade to a Sandy Bridge combo or something like it... 'Cause I don't believe that so many games make a profit from tri-crossfire...

EDIT : Metro will already max with a pair like that, and the thing about high end gear, especially CPU,s GPU,s Motherboards ect are never futureproof. Technology moves too fast for anyone to guess and say OH I PREDICT THIS GPU WILL REMAIN TOTALLY AWESOME FOR THE NEXT 3 YEARS! no that doesnt work, i mean look what happend to the Radeon HD 5970? it used to be that 1GB VRAM was more than enough for any video card, now BF3 MAX just kicks the 5970 to the curb because of VRAM limitations

Now, as with buying video cards, if you had a choice between 2 equally priced and performance setups 1 2 low end CXF and 1 high end, go with the 1 card because it will ensure compatibility with games, and you dont have to worry about scaling issues

Just disable Advanced DOF and you will be fine on Ultra 1920*1080... This card is still quite capable lol
