Here's a good stumper.
I have an old gx620 desktop, not the mini tower, that we use for LAN parties. however, we have decided to upgrade the gpu to play newer games. I upgraded the power supply to a 350 watt psu, but I'm running into a problem. according to most online sources, the pci-e 1.0a standard supplies 75 watts of power. but according to dell, their slot outputs only 25 watts. is this true, even though i upgraded the psu? if it is, what gpu's out there use only 25 watts? also, what cards ae out there that are known to work with this machine? I've heard of ati hd 4650's and geforce 9500's, but can't confirm them.
It WAS a pentium 4, and it was so slow that i ripped the motherboard out and replaced it with a optiplex 755 motherboard, so now the computer is a core 2 duo.
it now has a core 2 duo 3.0/6/1333 and 8gb of 800 mhz ddr2, running windows 7 64 bit. would the 5570 work? acording to this test, it only draws about 24 watts. also i could get a fanless model from HIS, which would have even lower power draw.
