not to sure if there is.. but, replacing a video card is probably 1 of the most easiest thing to do with a computer ( i would personally say), and wud happily make a quick little guide (taking out my current then putting it back in) if any1 would like this (thats if there isnt already 1)
FOR AN SLI INSTALLATION FOLLOW SLI1. WHEN YOUR UP TO IT...
(make sure computer is on before you start and preferablely you have anti-static mats---althought i never personally use this gear---)
step1.remove plugs and things out of the back of it...
step2. unscrew the old card from the back of your computer(newer computers use an easy de-attachable system)
step 3. pull out(being gentle and watching for other components)
step4. open new gpu(video) card
step5. find drivers and the card out of the box, place drivers to 1 side
SLI1. insert your 2 (matching) video cards in to the 2 designated slots.
SLI2. insert the screw/clip to secure them in place.
SLI3. connect them together using the provided SLI connector.(should go on the video card towards the back of the case-note you should beable to see 2 right sized gold fingers)
SLI4. start computer and install drivers
SLI5. (nvidia go on control panel then find.. nvidia control panel, then find the SLI enabeler (cant remember where as i currrently have 2 screens, tv + monitor) -----THANKS TO TECHSPOT TEAM-----
SLI6. then you should be ready to go extreme!!!!!!! =]
step 6. place video card in your old slot (make sure its the right speed for your new card)--note this is the time to clear out any dust from round the area--
step7.put the screw/clip back on-to the back.
step8. turn computer on and install drivers
step9. GO OWN SOME NO0BS! xD
