Best Nspire CX Hardware Revision?

[Celeron]

Hi, I'm looking for a used Ti-Nspire CX and I'd like to know what hardware revision is the best to get. I've heard that the CR4 can suffer in speed due to Ti changing the way the LCD operates. Should I opt for a CR3? Thanks.

Hi.

It depends :

• the CX CR3 and older are faster with Ndless programs
• the CX CR4 and newer are faster with TI-Nspire documents

Thank you, Ndless programs were my main concern so I will try to opt for a CR3.
