Are AMD computers compatible with POTC Online?

[Bellatrix]

I am currently looking for a new desktop computer, but
I can not decide which processor to pick. An AMD processor
is nice and cheap, but it does not last as long as a Pentium
core processor, which is way more expensive. I'm also
hesitating on the AMD processor because the system
specs for POTC Online asks for a Pentium core processor.

Any recommendations? Oh, and does anyone own
an AMD computer? Does it work with POTC Online?

Thanks in advance.
