I say a 5770. You could probably do with any single GPU card, but a 5800 series card might be pushing it and may decrease the life of your PSU. It just depends on how much power the rest of your system sucks up. My system draws about 470W from the wall under load, which with about an 85% efficiency is about 400W supplied to the system. This is with Furmark and Prim 95 on three cores.
 
They wouldn't be pushing it at all. The HD5800 series uses slightly less power than the HD4800 series. That PSU cold handle them easily.

All you guys have to do is check the link I posted and I'm pretty sure a 450 watt can handle alot of even todays hardware. I'm I run a GTX 260 that says recommended 450watt PSU, but its saying 450 for whole system set-up. Use the calulator link I posted.

Just to be curious I looked up the power usage of a Phenom II x 2, Regular Gaming Motherboard, Radeon HD 5850, 4GB of DDR2, DVD-RW, 7200RPM standard drive the grand total of power IS! = 432Watts.

Thanks for all the post.

There's a huge difference between say a Antec EarthWatts 450W and a generic 450W.
The generic might have been tested at 20C (completely unrealistic for a PSU), have it peak power (means sustained is around 300W at best), and have more amps on the 5V+ & 3.3V+ rails.
So that would be around 200W if not lower.

I'm just going off of the link and the facts behind what newegg recommends, I mean I built my PC off the facts, reviews, and ratings from newegg.com, I've also being using my PC for 1month straight and its working fine for me.

A GTX 260 would work out perfect for you I added together your current system and I took away your 9800GT and changed it out with a GTX 260 the max PSU required is a 450Watt.

Of course it all depends on your wants:

>Nvidia or ATI

>Money a lot or little

>Card Size low profile or regular

>Dedicated memory on card 512MB 1GIG DDR3 or DDR5

>Card Brands BFG, XFX, PNY and so and so on.

Just tell us a little more so we can send you links and ideas to your thread. Thanks man!

I have some questions that you need to answer:

Is your motherboard SLI or CROSSFIRE?

Do you know if you have an ATI or Nvidia chipset?

Would you want just one good card or two?

Would you be able to use newegg.com?

Are you USA or Canada or some other?

After you answer those questions I can find you a really great card and a good price as well.
