Looking to upgrade from 2 nvidia 7950gtx in dell xps700
I just recently inherited a Dell XPS 700 desktop computer that has a 700 watt BTX psu, I am looking to upgrade it from the 2 Nvidia 7950gtx video cards to a more powerful single Nvidia Card from EVGA with in the next 2-3 months. The problem I'm having with the decision is that after reading up this computer I read a lot of bad things about the upgrade ability of it due to the power supply and the amount of volts which isn't something I fully understand yet. I really don't have a set budget in mind and really just wanted to know if any one could tell me the highest video card i could go with based on the knowledge I have, which is minimum of the computer I own. What I want to use this computer for is FPS/TPS gaming and maybe playing around in the UDK/Cryengine.
I'm sorry if a similar question was posted but I couldn't find a tread search feature.
