Yo guys hello,
At the moment i am having xfx 5850,i`ve god some more money to spend so these days i`ve beeing watching 7770 review`s.I saw it overclocks very well,and most times beats 5850 at 1280x1024 resolution.Its a lot quiet than a 5850 and uses less power.What do u thing?I am going go fell a lot of differences if i upgrade?
Unless you really want lower power consumption, don't bother. The 7770 is actually a downgrade from a 5850. You might be able to get the 7770 to be a little faster than your 5850, but only if you can achieve a good overclock, which isn't guaranteed.
If you really want an upgrade, you should be looking at a 7870 at minimum. Even then, it likely won't make a real difference over your 5850 at your resolution, the 7870 is really meant for 1080p gaming.
