I've just gotten about 350 for my b-day and am looking to upgrade my gfx a bit and was looking for some input.
My Rig right now:
xfx 680i LT Sli
q6600 @ 3.0Ghz
4gb geil DDR2 800 ram
(1) xfx 9800gtx, original, not the +
Ultra 750watt psu
CM Storm Scout
24" Asus monitor
1. Should I just buy another 9800gtx and run Sli and spend the remainder of my cash elsewhere?
2. Would the 5850 be the better upgrade? Can't get the 5870, it won't fit in the case.
3. I've read some customer reviews that mention the 5850 having a hard time with the physics in some games. One review mentioned that anytime something would blow up in Crysis his 5850 fps would drop to 10fps. Has anyone else encountered this?
The 5850 will not have a problem with PhysX, it just won't do it by default but there are hacked drivers floating about that should let you use the 9800 as a PhysX card whilst your 5850 does the graphics, if you choose to go that route.
When something blows up in Crysis, that's not PhysX calculations happening on the GPU. As far as I know crysis does not have PhysX support. In Crysis things like smoke require more rendering power from the GPU, causing a drop in fps. This is true of any GPU, not just the 5850.
Of course, a more powerful GPU will drop from a great framerates to good framerates, and you won't notice anything.
