RAM: G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL
HDD: Western Digital Caviar Blue WD5000AAKX 500GB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive
GFX: XFX HD-677X-ZNFC Radeon HD 6770 1GB 128-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card
With that, to the best of my knowledge, everything there allows me to support crossfirex if I would like to utilize it. This was a benefit for me because if in the future I saw a need for it, I could do it.
But here is my question, along with the graphics card I just purchased, would I be able to use an HD 4300/4500 to crossfire with it right now? I ask this because my old Rig has the 4300 card in it, and I could strip it from there to use in the new one if it would benefit.
So the gist of my question is...
1. Can a 2nd gen graphics card (HD 4300/4500) be paired with a 3rd gen card (HD 6770)?
2. If it can, would it benefit my experience in games, such as WoW, Guild Wars 2, Crysis 2, ect...?
Thanks for reading and look forward to your answers!
