Buy another 5870 or wait for single gtx580?

post #1 of 7
Thread Starter 
Long story short, i have a 5870, since the prices are so low now i was thinking for another 5870, i have seen 5 series not getting great scaling.

The other choice is to wait for gtx580 to go lower in price 250$-270$.

I have heard CF issues with micro stuttering etc. Is that true? what should i do?

2 5870's are slower than a gtx 580 right?

I think, depending on clocks speeds, CF's 5870s might be on par or slightly ahead of a GTX580.

I had a quadfire 5870 setup for a little while and I tried some games and didn't have any problems. I mean of course a single card will always be better in terms of no microstuttering and such against two or more cards.

Also a 580's extra half gig of vram would be helpful for a 1080p monitor. I'd probably go with selling the 5870 and picking up a 580 whenever you can.

I don't see the 580 getting that low for quite a wile. Most times, 2 5870's are very close to the GTX 580 in performance. Buying a second one would be the much better value.

The 5870 is a VERY capable card, so I would definitely keep it and wait for 580 to drop in price. To answer your questions though, here are my thoughts:

I used to have Crossfire 5830's, and I had so many problems I swore I would never go multi-GPU again. There are several issues not only with games, but with Windows too, believe it or not. Different systems react differently, but for mine (AMD PHIIX4 945/4GBRAM/Etc), it just didn't work well.

However, if you really need the performance increase, the crossfire 5870's will really outperform the 580 (clicky) as long as vram is not an issue.

5870s in xfire beat a 580 pretty easily? They aint too far behind a single 480 either (around 10-20% depending on the game). I think they should be fine for the next 2 years or so

A single 5870 should keep you afloat for a good year or more. I highly doubt a 580 will drop to $250 any time soon too. I wouldn't hold my breath.
