I am thinking about upgrading my HD4870 to a new HD5850, but I am worried that the rest of my hardware might bottleneck it. I have the following components:
Gigabyte 785g motherboard
AMD Phenom2 X3 720 with unlocked 4th core
4 GB DDR3 RAM
700W Power Supply
HD4870 w/ 512 MB VRAM
24 inch 1920x1080 monitor
Given that I have this hardware, is it worth it to upgrade to an HD5850? Also, might it be a good idea to wait for the mid-year hardware refresh and see if AMD releases some improved version of their cards?
Yeah, sure. The HD4870 is still pretty good but the HD5850 will be a very nice upgrade at stock and twice as fast if you overclock it. Your PSU should be fine and your processor as well.
You can also probably Ebay the HD4870 for a nice amount as well to put towards the new card.
