430w PSU (ALL OC'd) Which GPU?

post #1 of 15
Thread Starter 
Ok, so I want to change the GPU in my sig rig, but without changing anything else, no particular reason just fancy a change. Whats the most powerful GPU I can get which will run off this PSU?
Everything is OC'd and/or overvolted.
Thanks !

I think a 6870 or a GTX 460 are borderline, 6850 is more of a safe bet; you probably won't jumper over 400W with any of them.

probably a 6850 as he said...don't think you'd have much room to overclock though

If you plan on keeping that high cpu oc, get a hd5770.

HD 6850 is safe because you overclock your CPU.
Anyway, just for information.
I got a system with Xeon X3440 Lynnfield (running at stock speed) with P55 Board, 2x2GB DDR3 Memory, 5 HDDs, 1 Optical Drive, 6 Fans, andd GTX 260 OC to 729MHz/1100MHz.
It consumes about 350 Watts in gaming. That's when I try Time Leap Paradise. Common game like Call of Duty Black Ops & Mafia 2 consumes about 330-340 Watts most of the time.

5770 / 6850 the only real safe options then? I wondered about the 5830? I just enjoy my current small efficient gaming rig but want a little more in gpu area.

You can check out the performance of the hd5830.... similar in performance to the 5770 but it sports a 256bit bus-width. 6850 is also a good option. If you notice voltage drop in the 12v or 5v lines, you can always turn off the cpu oc.

Well according to some Benchmarks I have seen it doesn't seem like the 5770 would be much of an upgrade. I was hoping for something a little stronger and as I said CPU is currently on stock volts, I can always lower RAM clocks/volts but I want GPU OC'd as far as it will go
Any more suggestions? Anything from Nvidia?
