so i just bought my first Mac Pro from eBay. It doesn't come with Warranty, but i was assured on here before that Mac Pro's are pretty dependable and durable, especially if you take good care of them (Which i intend to) so i have some questions: How can i stress test every part of the Mac to make sure it doesn't already have some issue that the seller might have not mentioned? i.e. the Ram / Motherboard and Graphics Card? can anyone recommend some apps that will tell me if theres anything wrong or damaged in the Mac? I'm wondering if there are apps that can tell if something is damaged from static or other issues due to mishandling. can anyone recommend any good upgrades and stores (uk/europe based here) for this Mac Pro? its a 2010, 12 core 2.66ghz Mac Pro with 16GB of Ram, and 5770 ATI Graphics card. 2xTB HDD's. an SSD would be one cheap way to boost performance. do i need a special tray for the Mac Pro to fit one in? i would like to upgrade the Ram but it is more expensive than i thought. have many of you had good experiences upgrading your ram at a cheaper price via Ebay? the Graphics card.. i would consider upgrading it, I'm not a heavy gamer and I'm not insistent on playing at the highest settings exactly either or the very newest games. if there is a graphics card that under £180 and can play current gen games at moderate settings then i would be interested. any suggestions on the GFX card? Mac Pro usage profile: Photoshop (very high/large resolution images/multiple layers) Heavy intense encoding of blu rays to build my own iTunes film library from my own BD collection light gaming now and again. lastly i wondered if anyone can recommend the best way to take care of this Mac Pro.. i.e. keeping it dust free regularly, any specific brand or type of compressed air?
