Windows 7: Upgrade from a GTS 450 to an HD 4870 x2

X2 is a single card solution and as far as I know it should be fine even if it's 2 gpus.

600w is plenty by the looks of the spec but u can never be too safe. Try googling psu calculator. First result should be by CM.

Yeah there ya go. Remember psus are extremely susceptible to aging. Having a 100w overhead on a brand new psu may last longer and would be a nice investment. 2nd hand works too

Of course second hand ones won't last you as long but seeing as to how this is a lan comp and prone to environmental exposure spending less would be ideal. That's my concept of a lan comp at least

I installed the new card:

It's really noisy, it produces a lot of heat, but using only 1 graphic core i'm seeing a nice performance increase in some 3D games. Now I'm going to use also the second core, but how can I enable CrossfireX in 3D games?
Oh, and like in Skyrim I have a strange issue... in main menu the screen flash and it becomes green, but only on main menu.

Should I let games detect the new graphics card?
And, I'm thinking that my C2D E6300 is bottlenecking the HD 4870 X2 really a lot

So, that is for now:
using only 1 core, Radeon 4870 X2 > GeForce GTS 450

and i noticed that both core clock and memory clock are locked to 500 MHz when i'm playing 3d games!
