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.

the calculator says I need 466W total...

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 bought this PSU 9 months ago when i bought the GTS 450...

finally, tomorrow i'll buy the HD 4870 x2 for 80€...

I'm expecting a performance boost in heavy graphics games :)

Please let us know how it works out.

Yeah keen on finding out how those ol beasts will perform now. I used to have em too

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!
