i dont really care about price :) i want a pc that can run xiv decent on high
well, the 465 is an older, hotter, more power using card. The GTX460 is approximately the same performance, but less power usage/heat [or so I understand]
The GTX480 is the expensive step up, is roughly comprable to the ATi5870 [argument about performance differences, but no argument that the 480 uses more power]
The 5970 is 2 5870 GPUs on one card.
Unfortunately, you do not list your PSU. The PSU is a huge factor in overall computer performance.
As to why your scores are so low,is a good question. The Asus G73 LAPTOP in my house gets 3700's low/2150ish high. This is with a 5870m, roughly comparable to a 9800 GT[x?]
After your PSU, I'd check your temps with HWmonitor to see if you're throttling down due to heat. If the system is more than a month old [the older it is, the more important this step is] I recommend blowing the whole thing out with compressed air.
Also, verify your GPU power is properly and securely plugged into the card.
That's all I can think of off the top of my head with the info provided. Edited, Aug 16th 2010 12:17pm by seneleron
