I did a post awhile back - can't find it.
Here's what I have.
XFX 680i Sli MB
Q6600 Quad
700 Watt Ultra Power Supply
ViewSonic 22 W. Screen
4 gig OCE Premium v2 Ram
My thoughts, prior to Quad install - "Boy", will the 8800GTS fix my fps problems, which were from 12 - 22 fps, and eye-candy just sucked.
WELL, the 8800 GTS helped, minimally - I "finally" understood that the FSX cpu intensity was just too much for the Single Core I was using - so made the investment in upgrading for the "future" with the Quad setup.
WELL, in summary, I'm a very happy camper now - "WITH" the help of a fine fellow simmer who walked me through overclocking my quad - great guy -
I have my Quad and GTS heavily overclocked and I am getting 29FPS at heavy sites such as LaGuardia & LAX, Vegas, etc.........and I have experience FPS's in the range of 78fps - 108 fps while flying - No blurries, no stutters, and the EYE CANDY is phenomenal.............I use xGraphics and Ultra Terrain X - which help with eye-candy with no fps hits - not promoting the products, but they work wonders for me and the eye-candy.
I know one thing for SURE - even with a quad, you still have to overclock in or to get the fps's you are trying to achieve...........FSX is just a glutton on cpu's -
I have also learned through my friend - Hey guys - a "constant" 29 FPS is "all" we for beautiful FSX experiences - you will not see any difference between a locked 29fps and an un-locked "unlimited" showing 78fps.......
I hope the SP2 (Dirx X) will help even more.
FINALLY, I just installed a Corsair Nautilus 500 Liquid Cooler to reduce the temps due to overclocking - and it's NOT enough cooling - I'm having to RMA and upgrade to a larger more expensive cooler...........but, again, I want to overclock, and heat is a by product of oc'ing.
I am very happy now and doing more flying and "tweaking".
Hope this may have helped - Not trying to discourage, but to encourage. It's a drawen out process - lots of reading, lots of tweaking, but the end-results are "most satisfying" -
