I currently have an 8800 GTS. Should I purchase a 9800 GTX / or GX2 or should I just put in another 8800 GTS. Are there any performance charts that compare these two setups? I'm not sure what would be the better future investment or price vs performance ratio.
Edit: I'm sorry I have 8800 GTS not 8600 GTS
