I have an i7 X51 R1 (2 years old). I do not use this for gaming--only for webcasting. But the nvidia card puts a white 'haze' on the output. I put in a Radeon HD 7770 and now the webcasts are crystal clear -- but the driver crashes every now and then, ending the webcast (I DO have the most recent driver).
So, I need a new graphics card, but not one that will force me to upgrade the PSU. Gaming performance is NOT an issue at all--I don't need the greatest card out there, just something along the lines of what was in there originally (a 460 gtx I think).
I'm not a hard-core computer guy, so I'm not that familiar with this stuff. What would you recommend?
