I debated going to a PCI-E motherboard not long ago but decided to upgrade what I have.
I have P4 3.0 Ghz cpu overclocked to about 3.2 normally but I have it at just over 3.0 right now. The graphics is a geForce 6200, PSU is Ultra 650 watt and I got 2 GB of Ultra RAM.
When I first saw the lower priced card, I thought it was a version of the 3850. Sorry about that. My mistake. I looked at some tests comparing the 3650 to the 3850 and um, definitely going to go to the 3850.
Basically, then, this PC is "done" as I can go no further. (I do plan on more storage but.......next "big" step is a G-25...just saw they dropped average of $40!))
I know any further than this I will need to build a new PC and if with this card, I can run GTL and GTR etc, that's all I require. (for now..LOL)
