I'm looking for quite a technical answer here, despite the amateur sounding question.
I've got a 2006 era 17" Macbook Pro (primarily running Windows) which is limited in a number of key ways. For one, the motherboard apparently won't support more than 2GB RAM. Secondly, the CPU is a coreduo, which won't support a 64-bit OS. I'm limited to 32-bit Windows and Snow-Leopard.
I've thought about getting an SSD, but the spec says the Serial ATA bandwidth is 1.5 Gb/s so I don't know if an SSD is really going to make much of a difference? I've tried a Seagate Momentus-XT Hybrid drive in it, but I got a lot of GPU artifacts which may have been due to the slightly increased power draw of the Momentus (the issues were only on battery - they went away when plugged in). And I didn't notice a huge difference in speed. I've done all the usual windows trickery to speed things up but the machine is still quite sluggish under load.
I'm fully ready to hear that there's nothing I can do to speed it up but I thought I'd ask in case anyone has any genius suggestions.
UPDATE: I know this question is pretty much dead but I said I post my WEI score, so here it is:
Windows Experience Index OVERALL SCORE 4.4 Processor Genuine Intel(R) CPU T2600 @ 2.16GHz 4.7 Memory (RAM) 2.00 GB 4.8 Graphics Radeon X1600 4.7 Gaming graphics 1015 MB Total available graphics memory 4.4 Primary hard disk 146GB Free (242GB Total) 5.5
UPDATE 2: I have a new machine now, so this question has really just become academic. This machine used to fly under Windows XP. I played BioShock on it with passable framerates. Now under Windows 8 the performance is awful.
Windows 8 is supposed to be less resource intensive than XP. (Note that guy has the same CPU family as mine - 32bit core duo - and only 1GB of RAM) I've turned off indexing, disabled Dropbox and the disk usage is still at 100% almost all of the time. Opening Chrome takes about 10 seconds. Sometimes the whole machine freezes up for anywhere up to a minute before coming back. I've run some (but not all) of the harddrive tests in Seagate SeaTools and the reports are good.
