If I ever build a new rig, perhaps when the 939 Opterons become available, I'll need to decide whether or not I want to gamble $30-40 that I'll ever make use of SLI. (I know this has probably been hashed over twenty times before, so my appy-olly-logies in advance.)
I'm a best-bang-for-your-buck tightwad, so with that in mind, to date, has anyone yet obtained a "best-bang-for-your-buck" result by going with SLI? Was the extra $30-40 worth it?
Obviously, it's almost never worthwhile to purchase two lower cards when they end up being more expensive than a single more powerful card that outperforms the two lesser cards SLI'd. The value would come from purchasing one card today and then purchasing an additional card a year or two later at rock bottom prices. The problem is--amazingly--the prices of older cards aren't dropping nearly as quickly as they should. Video card prices would seem to have amazing staying power!
For example, if you already own a 6600 GT, perhaps it would be worthwhile to add another one for, say, $80, but in practice the cheapest new card is $130. So you might try to get a used one off of eBay for $60, but we all know how eBay works. I never cease to be amazed at how much eBayiots are willing to bid for a used item in uncertain condition that may or may not be shipped to them, even when the seller has almost no feedback.
[For example, recently, a guy with 8 feedback points who'd only sold one or two items garnered $202 plus shipping for two used PNY 6600 GTs with little description other than his answers to my questions at the bottom of the listing. I was hoping to win the auction for under $140 and just do a local pick-up (no shipping cost, less risk of getting dicked over). But when you start talking about a cost of $210 it would be better to get a spanking brand new x800gto2 or to spend more and get a single 7800gt for $300.] That isn't an isolated example; I've seen few video card auctions that I thought ended with a good price relative to the seller's feedback rating.
If you had a single 6800 GT today SLI wouldn't do you any good since the 6800 GTs are going for about $260 new (after rebates). (Finally--the retailers grudgingly lowered the prices of an outdated card down to $250.) In this case SLI wouldn't do you much good because you'd be better off getting a single 7800 GT for $300 and then eBaying your 6800 GT.
SLI would make more sense if, say, you could buy a new 6600gt for $100 or a new 6800 GT for $180 and if eBay buyers were wiser and more frugal (allowing you to get a used 6600gt for $60 or a used 6800gt for $120 from a reputable seller).
Perhaps the best path would be to get a non-SLI mobo that can be modded to being SLI.
I'm sure this thread is unnecessary, but I just had to vent some at all of the eBay idiocy I've seen lately and also at the insanity of the current prices. The average price of a 6800 Ultra is more than the cost of a new 7800 GT !!! Those cards should be going for $220 right now.
