Hey All,

Was so excited to receive my new:
http://www.newegg.com/Product/Product.aspx?Item=14-102-948&SortField=0&SummaryType=0&Pagesize=10&PurchaseMark=&SelectedRating=-1&VideoOnlyMark=False&VendorMark=&IsFeedbackTab=true&Page=3#scrollFullInfo

today, until i started to play and BF3 was completely unplayable on any settings whereas I could play just fine on low with my ati 4850. I was getting a CTD a minute or two into every game as well would just freeze up no matter where I was. Have not messed around with any settings in CCC yet, although GPU usage did not seem high, temp. either.

Specs:
1280x1024
4gb ddr2
dual core 3.0ghz
ati 6780 1gb
162gb hd
600w PSU

After a bunch of research I see that my cpu is not really up to par, but how is it that a new video card has hurt my performance? less RAM available? I was able to play fine on low with the 4850, little lag in close quarters fighting which i upgraded to try to combat that with, but to avail as of yet. Any help or suggestions are very much appreciated.

It could be because you don't have PhysX. Frostbite 2 has a component called Destrustion 3.0 which requires a lot of PhysX processing.
As to why you could play it on the 4850, that's beyond me.

i wouldnt think a 6870 would use any more power than a 4850 buy is your power supply a decent brand one for starters, not that this would solve your problem but you definately need a decent quad core processor i noticed a big difference between my q9400 overclocked to 3.4 and my 2500k and prob about 6gb usable ram (my system regularly uses 6 or my 8gb of ram during bf3) if you want a decent looking experience with bf3

my cpu is intel e84000
i suppose before spending any money I will try to install 64 bit, if not then reinstall windows. Really thought i could run on high with just a gpu upgrade, everyone told me quad core would only be necessary for ultra, seems to very some very conflicting advice in that department. Thank you all for the suggestions.
