Hi,I have recently bought a Gigabyte GTX-560 non-Ti card that is overclocked by default (GV-N56GOC-1GI) and I see poor performance on games such as Crysis 2(15-20 FPS average everything maxed out) and Mass Effect 3 (20-30 FPS only AF disabled everything else on max) and ArmA II (15-30 FPS average all maxed out no AA),before I bought the card I was playing on my brother's rig but with my HDD's connected to it and got an average of 25-40 FPS on Crysis 2 and a constant 60 FPS on Mass Effect 3 and 30-45 FPS on Battlefield 3 all maxed out and ArmA II all maxed out without AA with FPS range of 30-60 on an ASUS GTX 550 Ti card both my brother and my monitor are the same running on a max resolution of 1280x1024 ingame and on desktop the graphics settings in all games are the same as they were on my brother's rig but now with an FPS drop ranging from 10-20 frames from the frames I got on my brother's rig,the specs are as follows:
2 GB RAM Kingston
1280x1024 Acer AL1717 monitor
500 W PSU
Core 2 Duo E7500 @ 2.93 Ghz
My PC:
GTX 560 1GB factory OC'ed
DG946GZIS Mobo
2 GB RAM Kingston
1280x1024 Acer AL1717 monitor
500 W PSU
Core 2 Duo E7500 @ 2.93 Ghz
My brother's:
GTX 550 Ti 1GB
DG41RQ MOBO
2 GB RAM Kingston
1280x1024 Acer AL1717 monitor
500 W PSU (same brand as mine called Diamond)
Core 2 Duo E7500 @ 2.93 Ghz
As you can see the only difference between the 2 rigs are the MOBOs other than the graphic cards,so I have no idea why the lags are occuring though I'm running a more powerful card now,I can assure you that the HDDs have no role in this lag.So what's the problem and how can I fix this.
