Is GTX 295 more powerful than a GT 9600, Radeon 4870 x2? I have two Radeon HD 3870 in a crossfire config and I want to upgrade to a single card. Which way do you recommend I go?

GTX 285 however you cant slam a high perf card into a low perf CPU setup

The 295 card is rubbish for FS9 or FSX. Its a dual card which neither will use. Unless you are going to be using a dual card for games that actually use both cores the 295 is a waste of money as is your current crossfire setup is not using both cards in FSX I hate to tell you.. you are getting a shared % of each card in crossfire but never 100%+100%.. it will only ever equate to 50%+50% or 1 card

The best card for FSX is a GTX 285 but you cant expect that card to perform on a rig that runs DDR2 memory on a slow processor in FSX, nor can you expect that card to perform on a motherboard that is not PCIe 2.0 (modern chiptset motherboard)

I picked up a GTX 260 896MB GDDR3 for a song from one of the puter club members. He got it for his system and doesn't have PCI Express at all. I am getting excellent vid perf combined with my ASUS P5K-E mobo and Q8400 Quad Core chip.

Here's my rig:

2.20 GigHz AMD Phenom 9500 Quad Core
Board: Asus M3A32-MVP DeLuxe3072 Megbytes Memory
620 Gigbytes Free Space
ATI Radeon 3800 Series (2x)
450W PSU

Is this going to hack it with the GTX 285?

Also you said that the two video cards crossfired only operates at half the capacity each. If I remove one of the cards since it's only running half speed, will I get 100% performance from the remaining card? I need to free up some PCI slots.

You are only getting one card worth of performance in FSX with crossfire so removing one is not going to change anything with respect to FSX. Other games that use crossfire 100% will be effected by that though.

not even close

The PSU needs to come up to a minimum of 600watts and the system itself would be bottlenecked by it but you would see some improvement

I would suggest the 275 in your case. Even that card is more than the CPU and memory in this system will feed but its more reasonably priced than a 285 http://www.newegg.com/Product/Product.aspx?Item=N82E16814130478

The next step down would be a GTX 260

and the next down is a 9800GTX

@450watts I think you are already underpowering the system with 2 ATi cards in crossfire

Your power supply is definitely too weak to take on a newer video card and like I said with 2 ATI cards in crossfire I actually surprised that 450watt PSU is running the system. It must be screaming hot at the very least.
