Hey guys! I love my iMac to death, but since consolidating all my gaming to the PC, I've learned that the 2600 in it just doesn't keep up in Vista. So, I've been surveying different outlets for a used Mac Pro, and I ran across this deal: 2 dual core 2ghz xeon processors 8gb ram Nvidia 7300GT 250gb hard drive 16x super drive Airport extreme OSX Tiget $1450 shipped I asked the seller about Applecare, and he said it has expired. The computer is two years old, has never given him a problem. It was purchased as a refurb, and he still has the original brown box and paperwork. He says it's in great condition, but understands most people like Applecare on used products, and so it has proven to be a tough sell. So, my first question would be: Do you think it's safe to pull the trigger? Is it stupid to buy a used computer without a warranty? Or, if it is in great condition, should I jump on the opportunity? I'd be paying via PayPal if it matters... I certainly couldn't afford a new Mac Pro. I figure I can eBay my iMac (with Applecare) for about $1500, wouldn't you agree? So this would basically be an even trade. I can't come up with another $1200+ for an upgrade. My second question, is about a video card for Windows. I did a MRoogle search, but didn't see much, so sorry if this is old hat. But most all conversation has been about the newer Mac Pro. Not first-gen units. Basically, will I run into any trouble keeping the 7300 in there for OSX, and then placing an additional video card, say a 4870, in the system for use in Windows via Bootcamp. Is it difficult. Are there any problems in either OS? And lastly, anything else I should consider with the purchase?
