A dual-GPU solution is a supreme waste of money unless you are gaming at high resolutions and have cash to burn.
Now wait a minute... You just bought a 1950XTX and you're talking about dual GPU solutions being a waste of money? Value is not a simple quantity to define in many computing environments, but in the context of your recent purchase, this does sound a bit pot/kettle/black.
In the same post, I later explained my point. The performance gained by a dual GPU arrangement is far from matched by the price you pay. You mention the X1950XTX ... two of those cards in CrossFire would cost upwards of $950, depending on where you purchased them. The performance of the dual X1950's would not reflect the performance of one (1) X1950 x (times) two (2). It's only at
high resolutions that the advantage becomes more obvious; and still, it's an advantage which doesn't justify spending nearly $1,000.
Until the technology further matures, it's something better overlooked ... especially considering the exorbitant cost to run two decent (or high end) cards in a dual arrangement.
It all depends on what you're trying to achieve and how you set your priorities. If money really matters most, then quit gameing and go to work instead! Regarding SLI and XFire, remember that power requirements and heat management can't be ignored. These configurations are overkill and cost a wad of cash.
What you say is fair, just as what I said was fair. I was simply giving onimusha2000 some advice and trying my best to explain myself. Your last sentence well reflects my original "bottom line."
