I want to use an ATi Radeon 4870x2 in my new computer, but I'd also like to use a 22" monitor as well. Assuming I used this monitor for a long time, would it be better to just buy a regular 4870 1GB or would it be a better future investment to go ahead and get the 4870x2 even if it might be overkill now or a little more expensive? I plan on using it with 4GB of RAM and an Intel Core 2 Quad (Q6600) CPU. No crossfire right now, but most likely I will in the future after a couple years.
