Q: Should I SLI/Crossfire?
A: Generally no. SLI gains are impressive, but very few people need the performance increase compared to a single high end card. A single $180-250 card will handle pretty much everything at 1900x1200 and below. Dual card solutions not only include the cost of two cards, but also adding in a SLI/Crossfire enabled board, a bigger PSU, and sometimes additional cooling.
SLI isn't a good upgrade strategy either. Two SLI cards of an older generation are typically outperformed by one card of the current generation. Save that money and buy a new card in 1-2 years.
SLI is good for is people who game at extremely high settings like 2560x1600 with maxxed out AA/graphics options.
