Just bought some lovely 460's and placed in my "old" pc.

Thinking i could upgrade to i7 cpu and board later I decided to try new graphics card(s) out as my 9800gt was just about managing 30fps or lower on lowest settings in Bad Company2...also with the cpu running at 90-100% all of the time. Mostly 100%.

I'm a little dissapointed at the results as im getting 25 max fps with settings set to high and its sometimes jumpy.

I have made sure all drivers and physx is up to date pc is clean and running well.

Now don't laugh but could the problem be my old motherboard be constricting my new fast cards its a P5N32 SLI SE Deluxe with E6600 cpu. PSU is tagan 900w and ram is 4gb with 2 x 64gb ssd's in raid.

Heat isnt a problem either.

Thanks in advance for your replies

ahh soz its all stock not overclocked running at 2.4ghz core 2 duo ofc tried to overclock cpu using bios but fed up of it locking up and resetting bios. reviews on net say its not the best board to overclock due to chipset..i have tried and only got it to 2.43 ghz
 
aww ok thanks.. i couldnt find a specific answer on net..thanks for answer..time to save some more pennies and not tell wife...again:P
 
An I5 750 / 760 would be fine once overclocked to 4 Ghz.

The I7 doesnt really help much in games over one of those I5s.

Except that 1156 motherboard that do proper SLI/Crossfire are expensive and will cost almost almost as much as a decent 1366 board, which will do 16x/16x instead of 8x/8x on the 1156, losing around may be 2~3% performance on each card.
 
A system upgrade will mean not only a new motherborad and CPU but also new ram which isn't cheap.

You might want to look at getting a Q6600 2nd hand and seeing what sort of overclock you can get out of it.

But the thing is socket 775 SLI board tends to suck for overclock CPU, and can overclock a Q6600 to 3.2GHz average at best. A Q6600 overclocked to 3.2GHz with a pair GTX460 in SLI could still suffer low minimum frame rate due to architecture limitation. But you are right about upgrading to i5/i7 would cost a lot more.

Just realised that i3 build wouldn't work as he need SLI and that board is doesn't come with the licence. D'oh, more expense.
 
I'll upgrade in next few weeks, I will be looking at 930 i7 may over clock it to 4ghz with an asus board maybe asus rampage 3 or just asus P6X58D-E with 6Gb triple channel ram

thanks for replies i have looked at getting better cpu for this board but seems like il struggle to overclock it and its also money that could be better spent upgading..its only gonna cost £6-700 should last another 4-5 years lke this one has

Don't get the Asus Rampage III Extreme. It might have some extra features (which you most likely won't need), but nothing that worth double the price of the P6X58D-E. It's no more overclockable than the £150 range motherboard already is (because they are very good to start with). You'd better off using that money for getting a decent SSD, such as the Crucial RealSSD C300 64GB as a boot drive.
 
Tbh save yourself £40 and overclock the rig yourself.

I'd still go with i5 build myself, 8x/8x SLI is compensated by lower access times with an integrated PCI-E controller. If you overclock the 2% difference won't matter IMO. You could save further £15 yesterday when i5 760 was on Today Only.

Granted, the i7 is more future proof with its HT and all features of 1366 sockets. There's also a possibility of upgrading to hopefully cheaper hex core in the future.
