I'm looking to upgrade my current rig's graphics card to Power Color HD 7870 2gb
Here's my current setup
Processor: AMD Phenom x6 1090T
HDD: Western Digital Blue 500GB 7200rpm
GPU: EVGA GTX 460 768mb
PSU: Thermaltake TR2-600W
RAM: Gskill 2GBx2 (total of 4GB) DDR1600
I'm planning to upgrade RAM to 8GB as well.
My question is: With that current setup, is it okay to outright replace the GTX 460 with an HD 7870? Will I experience bottlenecks? Would it be better for me to get a new processor like the Intel i5-3570 than a GPU?
Another thing, local vendors here in my country have the Power Color HD 7870 as the cheapest one, other brands are 20-50% higher in price. Is there a reason not to buy the Power Color HD 7870?
