I have an X700 PCI-E which has died on me and needs to be replaced with something similar or better. PSU is only a 300W FSP (which has coped with the X700 fine). I would much prefer a passive card.
Reading around the X700 is slightly slower than a 6600GT and comparable to a HD2400Pro and X1600.
I am unsure between the following from Scan:
NVidia 8500GT
512MB XFX 8500GT PCI-E (x16), Mem 500 MHz GDDR2, GPU 500 MHz, 16 Cores, D-Sub, Dual Link DVI-I PASSIVE
£35.24
ATI HD2400XT
256MB Sapphire HD2400XT PCI-E(x16) 64Bit 1400MHz GDDR3 GPU 700MHz CrossFire D-Sub/DVI/HDTV Retail. Passive
£32.89
ATI RX1650 Pro
512MB Sapphire RX1650 Pro, PCI-E, 12 Cores, Mem 1350MHz, GPU 450MHz, Dual Link DVI/S-Video, Retail FAN Cooling
£29.49
Which would be better?
