I recently bought a Cyberpower PC Gamer Ultra w/AMD FX-4100 I did so believing that I’d replace the graphics card with an EVEGA GTX 560 Ti I had purchased last year for my previous computer, which had since died. That computer, the one that died, I had given to someone I’d thought I could trust. I mean, WTF?. Unfortunately, when I got the old PC back from the clown he claimed that it was the motherboard that had fried. I tossed it in the basement and bought the new Cyberpower. Not right away of course because I am handicapped and living on disability so money is short. So now, after more than a year of scrimping and saving I was able to buy my new PC and intending to swapping out the cheesy card that’s in there (the 520) with the GTX and figured I would also need to upgrade the PSU to a 650-850w unit. Not a problem since at that point I had about $150. So I dug the old tower out of the closet and low and behold I find that he’d taken out the GTX 560 Ti and replaced it with a GT 210. Scum-bag. So now, the $150 I’d saved to spend on a PSU and RAM is not enough to get another card like the GTX 560 Ti and a PSU! I wonder if anyone out there might offer this novice some advice about getting this all figured out. I’m trying to understand the SLI thing with the understanding that I may be able to get 2 - cheaper 1GB cards that I can run in an SLI configuration that will give me the performance I need. The only things I do on this computer are listen to Spotify or stream music through Pandora or 365FM etc. as I spend countless hours perfecting my Google Sketch up skills. I don’t game, sample, edit or whatever of movies et al. The problem is that this seems to tax my system and causes SketchUp to crash. I’m hoping that this is due only to the poor quality card/PSU combination. It seems that when my drawings are larger that 15-20mb this happens often. Does anyone have any suggestions as to how I might remedy this? Is it possible and will I see any gains with two less expensive cards run in SLI configuration? . Am i really just S.O.L? I don't know if I got it right but I've tried to attach the spec of my current system figuring you'd need this information.
