Based on GeekBench alone, so take it for what it's worth to you, the RMBP is about 2x faster than what you have. The RMBP clearly has a better video card which I'm sure After Effects and action games will make good use of.
 
The new processor has lower clock speed, but it will be SIGNIFICANTLY faster.

1. It is a much faster architecture, Core i7 (Ivy Bridge)
2. It is quad core. 4 cores. Your last CPU only has 2 cores.

CPU power = Architecture * Frequency * # of Cores

So a 2.3 GHz Core 2 Duo would be slower than a 2.8 GHz Core 2 Duo, but a 2.3 GHz Core i7 (Ivy Bridge) is way faster.
 
This may be a dumb question, but I want to make sure before I make any decisions. For heavy use of the Adobe Creative Suite (mostly Premiere and After Effects) and gaming, which is a more powerful computer?


MacBookPro5,3 (The computer I have now)
Processor Name: Intel Core 2 Duo
Processor Speed: 2.8 GHz
Hard Drive: 500 GB
Memory: 4 GB

OR

MacBook Pro with retina display (The computer I want)
Processor Name: Intel i7 Quad Core
Processor Speed: 2.3 GHz
Hard Drive: 256 GB
Memory: 16 GB

Obviously I'd be making a huge leap in terms of RAM, but I am concerned about the drop off in processor speed. Will that be noticeable?
Retina MacBook Pro.
 
Your comparing a 2.0L Ford Focus to a 1.8L F1 racing car

One has less "mhz" but which do you think is faster.
 
No offence, but this thread is funny when you think about the people buying MacBook Pros. Expectation != reality.

Especially in the context of this quote from the Engadget review:

It's perhaps more friendly for novice users, but remember: this is a laptop with the word "Pro" in the name.
