I have a Dell Inspirion 530 (~6yrs old) that I'd like to run some games on. It has a Q6600 (Intel Core 2 Quad processor @ 2.4ghz), 3GB DDR2 memory, and 2 SATA drive attached to the OEM PSU. I'd like to add a budget GPU (HD 6750 or HD 7750 or equivalent) to the machine.
Will upgrading the stock 350w PSU to a Corsair 430w PSU be a waste of time? I just purchased the Corsair CX 430m (modular) but think I made a rash purchase.
