Crossfire or Single card?

[magicroundabout]

currently i've a 512mb 4870 Sapphire.

I'm in the process of getting a new 22/24" monitor with res @ 1920x1080 or 1200 depending on which i buy.

Now for a graphics upgrade am i better off getting a second of my cards for £129 inc or sell mine and put funds towards a single faster card?

Looking around at reviews the 512mb Crossfire scales quite nicely but just want advise on whther it'll be my best choice for bang for buck

at that res you are going to want the best single card, i would go for CF

many others will probably say overkill for that resolution, but i beg to differ.

If you look at this roundup comparing cards you'll see its worth just sticking with the 512 you have and adding a 2nd, 2 of these in crossfire outperform a 285 even, and in some instances crossfired 1 gig cards (L4D, CoD:WaW and Crysis:Warhead for example) strange but true
Edit: thats at 1920*1200 with 4xAA and 16xAF

cheers for the replies.

hadn't seen that Tech Report so cheers. So basically for £129 i'll be up there with a 4870x2 but by saving over £70

well i've ordered myself another Sapphire 4870 512mb card @ £129 + Del.

Looking forward to getting this now and seeing how it performs in real world tests.

Too late but I would have said no. 512mb + 512mb in cossfire = 512Mb and with 1920x1200(or 1080) that is not ideal. A lower 1Gb card might be much faster in some circumstances.

Going by most benchmarks about at the moment that doesn't seem to be the case. Looking at another 512mb 4870 myself; at 1920x1200 and below it performs better than a 4870x2 in most cases!

well i shall try it and see.
if it starts to fall on it's rear end i shall sell them and then look at getting a single card.
