So there is this 2010 2.8GHz quadcore I just bought (will pick it up later this evening) and while it should be sufficient for some year to come I'd still like to push it in some corners. - USB3, just buy any PCIe card or do I need something specific ? - it's only 1 CPU and I can't really upgrade to a 2nd (making it 8 or 12core) ? - RAM is limited to 48GB (16GB allready installed so not really a current issue) ? I also have a 60GB SSD I might want to put to use here. Can I somehow merge it with the installed 1TB HDD to a fusion drive ? If not whats yout opion and Seagate's Hyprid drives (have a smaller/older one in the G5 but that ain't used for OSX) ?
