[Cube] Cube Giga CPU replacement question

[Michael Blossom]

Since the CubeOwner forums are down, I'll try this email list -- I'd 
appreciate your opinions.

Two years ago, I bought a Giga 1.2 Ghz (7455) upgrade with L3 cache.  
It was great for a while, then failed.  I sent it back, and Tim at Giga 
is offering me a choice of a free 1.3 Ghz *without* L3 cache (also 
7455), or a $133 credit toward a 1.8 Ghz 7447, which would bring the 
price to $166.

If I take the free 1.3, I only get the one remaining year on my 
warranty.  If I take the discount on the 1.8, I'll get the full 
three-year warranty on the new processor.

First question:  Is this a fair offer?  If the 1.3 had L3 cache, it 
would seem fair to me, but without it I'm not sure if I'm getting a 
replacement that's not as good as what I paid a lot more for a couple 
of years ago.

Second question:  If it is a fair offer, which should I take?

Thanks,
Mike
