Hey, i'm from India. I'm stuck between Dell XPS 8300 and alienware x51. I'm not interested in custom build PC, couple of my friends have heating issues and it is cheaper to buy a branded one compared to their custom build PC.
8 gb ram
intel HD 3000 (I would be manually adding a 560 ti gtx to the current system, existing PSU 460 ~ 500 Watt i think)
555 GTX (OEM)
I would like to know if i would have to upgrade the PSU as well for the dell xps for the 560 ti to work. How much would be the performance difference ?
