Default crossfire question

So i've recently discovered that 4770 in crossfire will do pretty well, and it seems like an economical way for some performance.

anyways, i was wondering if my psu is enough to handle it?

Coolermaster Extreme 550w ATX 12v V2.01 20/24 Pin ??

or am i better off at this point in maybe getting something like the 4870?

thanks!

it's not all the game that do well with crossfire, ( or sli) it's easy to find a card that will perform more than 2 x 4770 or 2 x 4870

I was pulling about 360W at the wall with a pair of 4770's under full load. I'd be concerned about the 16A+16A 12V rail on that power supply though.

i'm pretty much a noob at this, so i guess you're saying there will likely be problems with my current PSU? So I'm probably better off getting a single 4870 then?

I'm just looking for a cheap upgrade in the meanwhile for my graphics card from the 8600gt i've got.

Probably a better idea to get a good single card over two lower ones in CF. What is your budget and current MB? I would go with a 4870/4890 or 260 if you have around $200 to spend. Will be a huge diff over 8600GT

With 1 card, depend on the card, I sugest 4870 or GTX 260 and under your PSU will be fine. Short but fine.

Ask for more.

thanks guys, yeah i'm using the ASUS M4A78T-E mobo.

ATM my budget is preferably under $200. I'm currently leaning towards the 4870...anyone have any brands they'd suggest?
