a) Will I at least have a smooth user experience, like I did with Deep Rybka 3?
b) Is it worth buying Deep Rybka 4 rather than single-core Rybka 4? Roughly how many points difference do you estimate we are talking about? Also, again roughly, what rating do you think Deep Rybka 4 and Rybka 4 would get on my computer? (also-- 2 Gigs RAM, Dell, stand XPS issue at the end of 2006).
Thanks to anyone who can help.
You should not be using a 32-bit system for either Rybka. You want a deep version on either XP Pro-64 bit or Windows 7. (I would be interested in what the experts say is the difference in speed on the same hardware of Windows 7 vs. Windows XP Pro 64-bit).
The difference between a 32-bit and 64-bit system is huge. Also don't waste time with single-core system even if you are a casual user of Rybka.
I use Rybka for analysis of correspondence games. My anecdotal experience of R4 over the last 24 hours for a game from the finals of a major tournament that started in 12/07: R4 is much, much stronger than R3 based on infinite analysis of the same lines done in R3.
I was shocked at the price of R4: $119. Based on the huge improvement over R3, I would have expected a price closer to $200 for Deep Rybka 4 Aquarium.
I have no choice about my system, so although I understand it would be better to have 64-bit, I'm not buying a different computer, so I'm stuck with 32 bit. I know the difference can be near 100 points, but there is nothing I can do about it.

If you were going to be using Rybka for hardcore competition in the Playchess engine room or for Computer sanctioned correspondence chess, then yeah, 64 bit might make a difference.
BUT if you are going to be using Rybka 4 for your own analysis or as a playing partner or for your own engine-engine matches for fun....32 bit is just fine.
And you get the 64 bit version with purchase anyway so if you ever do upgrade you won't have to buy it again anyway.
