My MacPro 4 (mid 2010) died a couple of weeks ago. I replaced the graphics card (a reconditioned like for like card) and the mac is again up and running. But it is struggling. I've watched many a video on replacing the CPU and graphics card for powerful up to date versions, but I'm confused now as to what to buy. It seems that I'll need to update the firmware before I can upgrade the graphics card, but I'm getting messages that say that I'm no longer able to update this. The screen shot details what the machine has and what it will and won't do. Is there a more powerful graphics card that I can install without having to update the firmware? Or is there a firmware hack that I can load modern graphic cards onto? As for the CPU, i was looking at a 3.33ghz but what brand to buy? Please bear in mind I'm a novice at these things and apologize upfront to tech savvy contributors. I love my MacPro4, and don't want to lose it. I'd be grateful for any advice.
