Would it be smarter to buy 1 300$ gpu or to buy 2 older 150$ gpu's and sli them?.
always 1 gpu
- less power
- more reliable performance
- you can sli you good single gpu in the future
- you don't rely on drivers for resonable framereates in games
Yea sell your GPU while is is worth somthing. Use the money to aid in the purchace of a better GPU.
Higher fps with SLI or CrossFire can be deceiving. Framerate increase but so do input lag - it takes longer to see your movements on the screen.
