So, thanks to OpenEdge1, I did get ATITools to help make sure my fan stayed on and kept my card cool. Hellgate ran like a dream. I played for a while, then logged off, started charging my iPod via the USB and went downstairs. Later that night, I decided it was time to run a couple of AVs before bed, only now my PC's frame rate was chugging again.
Temperature = Fine.
Fan = Fine
HDD = Defragged, Cleaned, 25GB of space left at the moment.
Yep, it seems it may be my power supply after all. The new card requires a 350w AT LEAST PSU. My PC runs on an old 250w one. Crap. Now, I talk to Dell they tell me that my motherboard is not intended to run higher than a 300w PSU, and upgrading could eff up my system.
Any validity to this statement? I want to upgrade, but not at such a risk. I'd rather lower the life of my video card and run on less power than lose my entire PC. It seems that as long as I don't charge my iPod while gaming, the system's fine and 250w can suffice. Should I just stick with what PSU I have and get a new PC next year around tax time? Or should I not listen to the yokel at Dell and get myself a nice 400-500w PSU that's compatible (I think these old Dells require ATX PSUs) and cross my fingers he's full of crap?
