replacing card

[stratman59]

Hi guys, I have a Saphire HD5850 running with a Asus P5Q pro with a Q6600, 4 gig DDR2. Playing battlefield 3 I'm getting reasonable FPS (45-50) on mid to high settings. I was wondering if I upgade to a 6950 or 6970 would I be able to set most of it to high settings and keep a good FPS or would the difference not really be worth the money? Cheers

You should get a decent boost as long as the Q6600 is at 3Ghz or better.

Looking at the prices there have been some deals on the GTX570 @ £240 so that may be an option.

Also rumours of a new GTX560Ti out soon which will be close to GTX570 performance.

Thanks for reply, what I gone for is a second HD5850 to run crossfire. Found a new one on ebay for £130. I have 700 w PSU so it should be enough the only problem I can see me having is space in the case...

Well according to this review its all about the graphics card and not much about the cpu for BF3.

yes but the cpu can be a bottleneck if not clocked high enough

Well if you look at that review they clock the cpu down to 2Ghz and it made no difference to the fps from the same cpu at 3.3ghz.

Oh dear....

Big mistake going for crossfire. I'm using 11.90 and BF3 is unplayable with stuttering. Tried the 11.9 Cap 4 and no difference. Tried the 11.10 drivers and no difference. Should have just stayed with the one card which was perfectly fine.

**Update**
Well I figured something must be wrong as I've read other posts from people who are getting good results so I uninstalled and reinstalled the 11.10 official drivers and the the 11.9 cap 4 and hey presto it seems fine. To be honest adding a few extra options up to ultra doesn't really make that much noticeable difference as BF3 just looks great on medium and high settings.

***Update 2***
No, I was wrong still a pile of stuttering unplayable rubbish. Gonna try driver sweeper and another driver install. I can play everything on high settings with just the one card but with two it's useless, go figure!
