Upgrading GPU, what else?
my system is roughly 3-4 years old now and i'm looking for a graphical upgrade for gaming.
CPU: AMD Phenom II X4 840 3.20GHz
GPU: Nvidia GeForce GTS 450
PSU: OKIA-550ATX
MBD: Foxconn a88gmv
RAM: 4GB DDR3
right now i am thinking of upgrading the GPU to the GTX 970. not planning on SLI anytime soon
will my PSU be able to handle that card?
will i still be significantly bottlenecked by the other components?
what should be my upgrade process if my budget only allows for upgrading one component at a time?
thank you in advance
