Hello I have recently bought an VTX HD5770 (1GB) from Ebay and fitted it to my system but to be honest haven't really noticed an appreciable difference in performance over my old Sapphire HD4830 (512mb), even when overclocked to max settings in CCC.
So I wonder whether anybody here could help me understand why?
I have wondered whether there is a bottleneck somewhere.
Perhaps the CPU?
motherboard?
Here's my setup. It's quite old, but I don't have the cash right now to upgrade...
OS: Windows 7 (32-bit)
CPU: E8400 (Socket 775) - overclocked to 3.6GHz
Mobo: Gigabyte GA-73PVM-s2H
RAM: 3Gb (800MHz DDR2)
GPU: VTX HD5770 (1GB)
HDD: Samsung (I forget the model) Sata-II 360GB (I think, not that it makes any difference)
For example, when running Need for Speed Hot Pursuit, the average FPS rose from an average 43FPS in a specific track to 45 FPS.
In Heaven benchmark my score rose from about 480 to 530. In fact, most of the 26 tests actually appeared to run less smoothly on the 5770 so I was suprised to see any increase at all.
Also, the HD5770 fan appears to run very fast when idling, which is around 50 degrees C. It's much noisier than the 4830 and sounds like a jet taking off.
Due to the noisy fan and virtually non-exitant performance increase I'm actually considering re-selling the 5770 in favour of putting my 4830 back in to the PC. Is this normal???
