Bottle neck in my system

[Cappa-MK1]

hello & thx for the help.

I've just lucked into a bit of a sweet deal on a new GFX card a VTX3D 2GB HD 6950 PCI-E 2.1

http://www.amazon.co.uk/VTX3D-Radeon-6950-PCI--Graphics/dp/B004L5XZBQ/ref=sr_1_1?ie=UTF8&qid=1312351559&sr=8-1

I was wondering if my Motherboard is fit to get the best out of it, with it only been PCI-E x16?.

& is my PSU upto the new demands?


Im not desperate to spend cash, but if there's a bottle neck I'd like to sort it so i can game at high gfx with dual monitors. Thx for your your help.

That old x16 slot is the same speed as a pci-e 2 x8
which is the speed that sandybridge motherboards run when theyre in SLI or crossfire . It makes a tiny bit of difference to graphics performance . 2 or 3 % at most
