O2, R12k 300MHz, 320MB RAM, 36GB HD

[cenonicks]

I've had an O2 for some years but now finally have the space to use it so I thought I'd upgrade it a little and post the spec:

Yes, you've spotted that I haven't opened my wallet in years so I'm using a multilink adapter with a 1600sw (the 1600sw was my PC monitor for some years but now it can be with this O2 full time), not a flat panel adapter. If I can see an FPA at the right price I'll grab it. Anyone got one for reasonable cost in the UK?

When I found this O2 about 6 years ago it had an R10k 195MHz and a 4GB HD so I have upgraded those already recently. CD-ROM also died and replaced. I am absolutely loving how easy these things are to swap components - making PCs look ridiculously tricky by comparison. RAM upgrade next perhaps? I seem to have the bug .

I found eventually an affordable FPA for this O2 - so here is the changed hinv -vm:

...and here is the new gfxinfo:

Given I now have the display options for O2 for both MLA and the FPA, and that O2 performance is linked closely to its graphics performance, if anyone has software tests they would like me to perform to identify differences I might be able to run these. Certainly - and this is personal opinion alone - the FPA seems to give the more polished desktop experience.
