Hi, I'm trying to decide between these two GPUs for my purposes, which are: - no gaming - recording programs using EyeTV - transcoding those programs to AppleTV - using Handbrake to move my DVDs to AppleTV - running iTunes full time in support of a couple ATV boxes - using Aperture, iPhoto, iMovie, and Photoshop occasionally - run a VM or two At minimum I'd like to be able to have EyeTV transcoding video to ATV while HB is working since that combination tends to be more than enough to deadlock my MacBook Pro. I get where I need to be from a CPU and RAM perspective, but I have no clue regarding whether EyeTV Hybrid 250 or Handbrake exploit the GPU capabilities which differentiate, say, a GT120, GT130 with 256 or 512, or the 4850, particularly when moving TV shows from EyeTV native to ATV and Handbraking. That's my biggest bottleneck and if I can address it with any of these GPUs while using my iMac for more sophisticated photo and video editing and watching video on it - all in one stop - then I'd prefer to buy the cheapest graphics option and save some serious cash. And if I just need to bump to a GT 130 with 512, that works too. Thanks for your advice. Really appreciate it.
