Hi guys, I PC has an asus P8Z68-V LE Motherboard and sapphire 6870 1gb GPU.The motherboard has 2 PCIe Slots.It has two 16x PCIe slots but one of them was labelled 16x(4x mode). I am planning to add another 6870 in future.Will this 4x mode thing hamper the performance too much?
I have an 18.5'' LED monitor and it is very unlikely that I will add a larger one or additional monitor.What I want to know is whether this 4x makes crossfiring disastrous?
Another query is I use my pc only for 720p gaming. I am able to play all the games now(i've got a 2500k processor,8 gigs ram@1600mhz).How long do you think I will be able to continue without adding another 6870 for crossfire.
The last one, is it possible to crossfire 6990 with 6870?
