32- or 64-bits ?

Hi, I'm new here. I haven't even really used Corel DRAW yet.

We just ordered a laser engraver. Now the next step for me is to order a dedicated PC and Corel DRAW, which seems to be quite a standard software to design and format engravings. I'm actually training on the trial version these days.

My question is : should we get the 32-bits or 64-bits version of Windows 7 ? Is there any reason we should choose one over the other to optimize the use of Corel X5?

I believe most laser engraver drivers still run on 32-bits, so I'm leaning in that direction. I'd appreciate if someone more up to date could  tell me the status of X5 in this respect.

Thanks!
