ok i was thinking about crossfireing My hd 5770
but i don t know if i can
here are my pc specs
Cpu: intel core i7 2600k @3.4 Ghz
motherboard: asus p8h67-v
ram: 8gb @1333mhz
graphic card: hd 5770 stock clocks
psu: cooler master 700w silent pro

ok the problem is i can t sell my hd 5770 anywere so I thought about crossfireing it But my motherboard has
1 x PCIe 2.0 x16 (blue) And 1 x PCIe 2.0 x16 (x4 mode, black) *1
in the blue one is the hd 5770 and in The black mode as you can see is on x4 mode
is it worth buying a second hd 5770 and crossfireing it and also i read the manual and it said somthing that
if i want to crossfire i should disable something in the bios
and If it is possible will i have any big slowdowns
also i have a lg w2361v pf running in 1920x1080p
please helppp and thankss

i'm not agree with that the black one is only x4 so adding another card is waste of money just it give you half performance by the way if you take my advice then surely you would be much better and also you have already an excellent cpu h67 are not good for gaming if you want to intend it for gaming to adding another card look for a motherboard which have 2 PCIe (single x16) or (dual x8/x8).
Nowaday x8/x8 become more popular which performing the two cards like a fire. The best motherboard is asus p8p67 pro or the better one is asus p8z68 v pro. it's up to you!

With the 5770's, the loss of performance will peak at 5%, which is totally negligible.
