Worth replacing 2008 Mac Pro for upgraded 2010 Mac Pro?

[Justin1524]

Looking for opinions...

I have:

Early 2008 Mac Pro 3,1 lntel Xeon E5642 @ 2.80 Ghz, 2 processors, 8 ores, 26 GB RAM
Geekbench 3 scores: 1672 Single-Core/11,717 Multi-Core Score
Boot drive is SSD
Est. Street Value: $500

I'm considering replacing with:

2010 Mac Pro 5,1 2x Intel Xeon Westmere 6-Core 3.46Ghz Processors, 32 GB RAM
Boot Drive will be SSD
Geekbench Score: Multi-Core around 30,000
Est. Ebay price $1,800 to $2,200


I own a Pro Tools HD Native card and 2 blue 192 interfaces. I don't want to go the Hackintosh route and I just can't stomach the price of a trash can Mac Pro.

Pros/Question: Will going from 11,000 to 30,000 multi-core score give me a performance "high" I will seriously notice when it comes to tracking with plugins natively and latency?

Cons: I'm not considering future of USB 3/Thunderbolt etc. Old machines eventually die (e.g. power supply, MB - anything could die at any time) Yet Mac Pros are built very well.

Stick with what I've got? Spend the money? Hold out for the trash can mac? Wait even longer for the Mac Pro prices to come down? What say ye oh Pro Tools HD brothers? I know this question is subjective, just looking for thoughts.
