Whats up tomshardware people!

This is my first account, first post, so please don't hate if its a repost or if anyone asked this question already! I recently got a new computer set up, but it has a very crappy video card(VisionTek ATI 2600 Pro). Its decent enough for some games, but definitely I want to max out my computers potential. I have a ZALMAN ZM600-HP 600W power supply, and I was curious if its capable of handling 2(two) ATI Radeon 4870? Pretty much I need advice on what video cards to crossfire, and if my PSU can handle it? I need suggestions and advice, and I definitely don't want to risk messing up my new computer!Please help me out, and feel free to email me at Thanks tomshardware & I hope to hear from everybody soon!

Happy New Years!

So far I am deciding between 2X 4850 or 2X 4870. It seems like 4850 runs at lower wattage? Reading up would like some advice!

i would move towards a 750 for a 2x 4870

600 sounds fine for one but would probably need more for two.

and yes the 4850 will take less power but not by much.
