I stumbled upon 2 mac pro's (used) here are their prices: $600 for the first and $850 for the 2nd MAC PR0 2008 MODEL Two 2.8GHz Quad-Core Intel Xeon processors 4GB of 800MHz DDR2 ECC fully buffered DIMM ATI Radeon HD 2600 XT 256MB (two dual-link DVI ports) 320GB Serial ATA 3Gb/s; 7200 rpm; 8MB cache 16x SuperDrive with double-layer support (DVD±R DL/DVD±RW/CD-RW) Bluetooth 2.0 + EDR OSX LION 2ND) 2 X 2.66GHz Xeon 4 gigs of ram OS - Snow Leopard Stock - 250 gigs hard drive Added - 2X 500 gig hard drives DO you think I should consider buying these Mac Pros? (The $600 one is probably sold now though because of its awesome price) Are their video cards upgradeable to more recent cards (e.g. 2010-2012)? (possibly of more intensive Photoshop/ aperture). Is this a good deal? I know I can get Mac mini for same price but the upgrades in this are endless and so I can always have as much RAM as I need, HDD or SSDs, and if I need a better video card I can also upgrade that. Also Mac Pro users how long have you had your MPs? Are they still good after X amount of years? Thanks in advance!
