If I wanted to upgrade to GeForce GTX 295 what do I need? Would it be easy?Would my system support it ?
If you upgrade the power supply,maybe.
Dell power supplies are generally pretty good, but the 360 watt unit provided in the Studio XPS certainly won't provide enough power for the addition of a GTX 295.
You're going to want to check the fit as well, I know that the GTX260 has been wedged into the Studio.
You'll want to keep the hard drive in the upper bay and set an 80 mm fan on the front floor of the case to help with cooling, as well.
