No problems at all with IB2.3 here on this A4000T/060, but I do notice eBay is especially slow. It would appear it's HTML coding is not the most efficient.
If you're sure it's not a memory issue, or a problem with P96/CyberGFX then try updating your MUI setup.
Bad MUI custom classes can be the cause of many such problems.
I have an up to date archive here:
