As I unfortunately cannot wait any longer due to a slower work productivity on my wife's current machine a 2.2 i7 Macbook Pro. (Mainly caused by software and gray screen system crashes with some spinning wheel freezes, fans revving up a bit etc..) Where would one have the better bang for buck, longevity wise etc. when going to a more powerful machine to handle 2D animation work? I can purchase an iMac with the 3.4 i7 for @$2300 + 15% tax, or I have found a used quad core Mac Pro 2010, 3.2 GHz with a 5870 and 6GB Ram for $2400. Where would the smart money go? Apart from waiting for the refresh, which I cannot. Mainly to be used for Flash Pro cs5.5 animation for television broadcast in 1080p. I find the current setup a bit "chuggy" when scrubbing timelines, exports, etc. I am hoping a more robust CPU and/or GPU would cure this bottleneck in my work.
