I have a early 2008 MBP core 2 duo 2.16 Mhz macbook (see signature) with the max (4GB) RAM and a SSD. My laptop carries a heavy workload (software development) and I have a lot of applications running and l run into a lot of performance issues (beachball, slow response etc.). What are my options at this point? I was waiting for the i5/i7 Quad core macbook pro to come out, but dunno when that will be. Should I just buy the latest core 2 duo and max the RAM to 8GB? My Page ins and outs are at 6GB and 1.5Gb right now, so RAM is definitely going to help. But I think the performance boost would not be so great and the new MBP would be a much better upgrade. What do others think?
