8800 GT died

XPS 720 with 1000W PSU? Unbelievable. Can you describe more details about your PSU (Provide us the amperes of +12V usually found on the label of your PSU). And Detailed model of your CPU example: intel Six-Core 3930K@4.0Ghz.

Now look at your budget, which is $400. It would make a good upgrade on your GPU, You can go up to 6970 or GTX 570 (Also the coming 7950). But we need to confirm if it's compatible or not with your system.

Nvidia only supply the GPU's, they don't actually manufacture them or the cards.

Thanks, once I have an option (read new card in hand) I will try that rather than throw it.

Dxdiag aren't correct sometimes. But just show us the label?

Yeah seriously (Up on the OP there).

I would take that $400 and buy some new ram and a mid-high end video card. 8gb of ram you can find for $40-50 and a AMD 6850 for under $160. Any higher video card will probably be bottelnecked by your cpu. Put the rest into savings.

A 380 watt psu would be enough for an 8800GT.
You hear people running around spouting off about how Dell doesn't use power supplies that are big enough to allow for upgrades.
When you're spending thousands of dollars on the flagship model,there is plenty of room for upgrades.
Those machines were offered with a pair of 8800GTX Ultra's, 750w would have been fine for that, but Dell went even further, bad, bad Dell.

PS; not giving any reccomendations for Dell, just know a bit about them.

What you don't seem to understand is that it is an oem machine, doesn't matter what would work, there was only 1 of 2 units that were put in the system and Dell doesn't use Corsair.
Yes I am the Delluser;
Dell 2407WFP
Dell PS2 keyboard and mouse for testing
6 piece Dell surround sound
Dell laptop in the bedroom
Dell laptop in the living room
Crappy old Dell desktop on the patio
Dell 375w psu on the test bench
Got a problem with that ?

there is a list of dc,ac, amps on the sticker, not sure which one is relevant....

You better post pictures here .

You are right. I did not put it correctly. The actual card is manufactured by the a 3rd party, other than NVIDIA. NVIDIA supply the GPU itself (or microchip if you want). To supplement my comment though, the whole fiasco WAS mostly NVIDIA's fault, so there you have it...

I will only show this:

It is quite clear it was their problem with overheating chips and poor materials decisions. And actually yes, they should have at least one person overlooking what their AIB's are doing at their factories, since it is their reputation (and money!) on the line!
