Nvidia 7900 problems

by Ronsin / January 24, 2009 11:58 AM PST

My system:
AMD Athlon x2 4600 socket 939
MSI ms7093
Nvidia Geforce 7900 GS
2gb DDR1 RAM
WD Raptor X hdd + unnamed Seagate hdd
Winxp sp3

My question:
I recently learned that 7900 series video cards are notorious for overheating, and mine runs at about 60-64 degrees C with the case open and no programs running. I've been experiencing slowdowns and freezes and the like after a few minutes of gaming, so it seems logical that my video card is running too hot. (on a side note, Speedfan is reading "remote 2" on the SMSC H/M block at 125 degrees C, is this a problem and if so what do I do about it?)

I've also started noticing games needing 512 mb of video ram, so I figure it's not a bad time to upgrade. I don't have the budget for a total rebuild and I can't upgrade either the CPU or mainboard because as far as I know the 4600 is the fastest CPU with a 939 version, and no 939 motherboards are being sold any more. I've narrowed my GPU choices down to an 8800 GT 512mb version, a 9600, or a 9800 GT.

Thoughts on these choices? Are there any other cards I should be looking at? At what point will my system be bottlenecked by the motherboard or CPU? The most strenuous apps I'm running are fairly recent games.

Thanks in advance!

60C is not hot for a video card (8800gt cards run at 80C+). download rivatuner to better monitor your gpu temps. also optimize your system for the games you play by following guides at tweakguides.com.

if you do decide to get a new card, 9800gt ($130) uses the same gpu as an 8800gt (now obsolete and hard to find) so they'll perform the same. 9600gt ($105) offers about 90% of the speed of the 8800gt/9600gt so let price be your guide.
