Hi guys. This has been puzzling me for a long time. I have Packard Bell ixtreme M3720 and I have noticed that the nvidia graphics that came with it are worst than terrible. The PC doesn't resize how bad they are. It has NVIDIA GeForce 7100 / NVIDIA nForce 630i. I'm interested in upgrading the graphics but wonder if I'll need a new PSU. I dread the thought of changing the PSU as It is a lot of hassle and expense. But if it has to be done it has to be done. I'm grateful for any advice. Lastly there are no previous modification to the pc except for the addition of a blu-ray drive.
Max output of the PSU is 250 watts
Intel(R) Core(TM)2 Quad CPU Q8300 @ 2.50GHz, 2499 Mhz, 4 Core(s), 4 Logical Processor(s)
4GB of RAM
