Here's the situation. I switched from XP to Ubuntu and I'm really happy about it but my experience (which was already just about "correct" on XP) in the only game I play (StarCraft 2) is now really critic in 4v4 format.
Here is the heart of my PC :
Motherboard = ASUS P5N-E SLI NVIDIA NFORCE 650I SLI C55
CPU = INTEL E4500 CORE 2 DUO BOX
RAM = CRUCIAL BALLISTIX TRACER 1GO DDR2 PC6400 (X2)
Graphic card = ASUS VGA EN8600GT SILENT/HTDP/256M
Do you think a <100€ graphic card could give me the little boost I need ? I'm not entirely sure about it as my CPU is also in concern to my mind. Yet, it is out of the question to change CPU because the motherbord is already obsolete (but for now, I have no use of USB 3.0, SATA 3.0, PCI E 3.0, etc.). Moreover, you can anderstand I don't want to renew MB+CPU+RAM just for a game. So, the problem is : Is a new graphic card would give me more FPS even with an already very busy CPU ? I heard the GPU load the CPU.. so I wonder if it would really be a good thing to put a 2-3X more powerful graphic card on a CPU already crowded in SC2. And just as a note, I heard too that SC2 was a very CPU focused game. It is particularly true for me because I use low settings (easier to anderstand what's going on => pro-gamer style ).
If the answer is yes, then I'd like to know about a fanless graphic card well supported on Ubuntu that could do the trick !
I already had a look and wonder about those :
ASUS ENGT440 DC SL/DI/1GD3
HIS H667PS1G iSilence 4 - Radeon HD6670 - 1024 Mo
For a bit less than 100€ you get NV GTX 550 Ti or for a bit more you get NV GTX 560 SE. A Core2 E4500 at stock speed is a bit slow however, if you could oc it it would be better. But do prime95 test to verify stability. Do not oc ram.
Display driver is necessary for your graphic card to work. If you are having any problem with your graphic card then one of the first things that you must do is to download the latest display driver for your computer and then uninstall the old and reinstall the latest downloaded drivers.
What FPS do you get in SC2? What graphics settings do you use (especially resolution)? Did you follow Starcraft 2 winehq tips and tricks?
After the recent changes (in both SC2 and Mesa/Radeon) I get ~ 40FPS in Starcraft 2 consistently troughout the game (starts at 60 and then tails off). Minimum settings in everything, but 1920x1080 resolution. The processor is AMD Athlon II X2 255 - not a very good one - and the GPU is AMD Juniper (HD6750).
