All right never really done this whole forum thing before (NEW) but have a serious question!! Just recently got a great deal on two brand new Visiontek 3870x2's on
Ebay ($130 each) Never opened I had to break the plastic! But my question is ok I put one in my pc for about a week and let me say that yes they are awesome but
decided to try out the second in crossfire even though my psu shouldn't be able to handle it! Well its working for now and from what I've read I should be getting bsod's
and frequent lockups and games cutting off restarts ect ect. This psu is a Cooler Master RS-500-PCAR which is now only rated @ 500watts (Mine is over two years old but
I take care of stuff so when I got it 600Watt is what it said) anyway the problem I am having is not about speeds at which everything works but FPS That are really not
that much better than a single X2 I have ran riva tuner while playing some games and will either read only two gpu's have activity or they all have partial activity like say
25% on all 4 gpu's (=100%)? The mother board is dual 16x pcie single but in crossfire its 16x + 4x pcie could that be the reason or is it underpowering the cards also im
not playing at high res 1440 x 900 so i should pump out some fps new drivers installed the hole 9 yards!
Games are as follows: Gears of war :90fps solid, bf2142 :110fps solid, cod 1,2,4 :100fps solid waw, far cry 2: everything on high dx10 30-40 fps, stalker clear sky: dx10
high 30-35fps, dirt , timeshift, crysis :flickers on anything above medium but on high is around 30-40fps, world in conflict 40-120fps up and down like a yo-yo.
Do none of these games support quad gpu's or is there something i need to turn on?
