So the GPU on my M1330 has been going crazy. white screen with colorful lines, black screen while im in the middle of something. so should i send it back to dell and get a new computer or something? also, im thinking about handing this one down to my brother and getting a new one. so far im looking at the dell studio line and the only thing wrong is not a great GPU. Sager looks very nice but a bit pricy. i want to stay in the 2000 range and i want portability/battery life/good GPU for warcraft and game design. anyone want to point me in a better direction? also idk how fast the processor needs to be for that stuff?
