Graphic Cards Upgrade for SH3 + GWX3.0

[Victor Schutze]

I noticed that I have 12-14 fps in Kiel or when I zoom down on my u-boot in the map, I am left with 8 fps. I am looking for a solution to this problem.

My rig specs are:

Processor: AMD Athlon 64 3500+ (2.6 Ghz overclocked through mobo BIOS)
Mobo: Asus A8N-SLI SE Motherboard Socket 939, Nvidia NFORCE4 SLI
Graphic cards : 2 of EVGA 01G-P3-N959TR GeForce 9500 GT 1GB DDR2 PCI-Express 2.0 Graphics Card in SLI.
RAM: 4 GB (3GB used by windows 7?)
OS: Win 7 Ultimate 64 bit
Sound card: Diamond XtremeSound 7.1/24 bit Sound Card ( XS71 )
PSU: PC Power and Cooling Silencer Mk II 950W High Performance 80PLUS Silver SLI CrossFire ready Power Supply compatible with Intel Sandy Bridge Core i3 i5
I exclusively play SH3 GWX3.0 with a long ( ) list of mods.
I would like to be able to enable heavier mods such as "fm interiors" as well.

So, I am contemplating to replace my 2 graphic cards with this choice:

My question to you people is: Does it make good sense? Does it worth it?
What will be the gain in terms of fps? Maybe I should consider changing the whole mobo/processor/RAM combination? Not the same price though....

Any thoughts?
