For the price of those cards NickN, you could throw in a few more dollars and have 2 x 7900GT's.
It also happens that the 7900GT is one of those cards that responds exceptionally well to overclocking, should anyone ever feel the need to do that. The 7900GT appears at release date with large factory overclocks in some models, giving further creedance to this.
I would consider the 7900GT an interim card while awaiting the next DX10 cards. $300 in a 7900GT is going to buy all the performance required for the next year or so in FS9, the cards for FSX haven't been released yet in my opinion. Spending 5 or 6 hundred on a better spec card now won't make FS9 run any better at all, (at least not noticeably), and the more expensive card will be just as outdated by DX10 by the time it's performance is required. That's how I see it anyway. OF course, if I'm wrong, and there are DX10 delays, another 7900GT in SLI at a later date is a very solid and economical solution.
Nobody knows what is going to happen by the end of the year or when DX10 will even become available.
There is a distinct visual difference between a 300 dollar video card and a 500 dollar video card when we are talking about the types discussed in this thread, AND Flight Simulator, which is different than other 3D games. You get to SEE MORE with the better card and the scenery appears, faster, sharper and further away.
FS9 automatically adjusts the amount of autogen and sight distance based on the hardware installed if the FS9.cfg file is correctly set up. Your expereince is enhanced because FS9 was programmed to throw MORE at the screen if the hardware is available.
There is a difference and Michael Greeblatt who is a tester for Nvidia, ATI and a Microsoft graphics consultant will confirm that.
Now, if you want to go on the premis that it is better to spend less now with the intention of definitely buying a new and DIFFERENT card next year or at the end of of this year, then I agree with the lower cost card solution. Otherwise I would still rather have 2x7900GTX 512 in SLI than 2xGT 256 in SLI for FSX. It comes down to budgets.
Personally, when I upgrade I will be going with either an SLI x16 MSI:
http://www.newegg.com/Product/Product.a ... 6813130037...or a DFI board with the best video card (or cards) money can buy. The processor will be either an FX60 or if I wait, an FX64 (due out in Q4). The memory will be rated to run a minimum of 250FSB with 1T enabled and I will not run anything less than an 800watt SLI PSU, probably a PC Power & Cooling unit.
That purchase will last me 4 years and I bet it will run anything I throw at it with maximum quality.
I would rather pay more now than nickle and dime myself to death over 2 years trying to get more out of a cheap purchase. That mindset ALWAYS costed me more in the long run and I learned my lesson years ago about going cheap. After the better components are purchased and installed, overclocking is nothing more than an unexpected BONUS. The components, specifically the memory and PSU will allow for aLOT of head-room in playing with overclocks and adding components later down the road.
My approach has always been to figure out my current budget, then consider what I will have to spend over the next year... then add the two together and go ahead and SPEND the budget+the year amount for the GOOD components. That mindset has never dissapointed me or let me down, ever.
If a small budget is all one has to work with, then that is just the way it is. Caveman asked:
