Er, what?
GPU's are far more powerfull than the Cell, it would be better if they got multiple GPU's and put them together, they can also do "compute" tasks just as good if not better than the Cell. (Think: Folding@Home as an example.)
The Cell isn't that powerfull, it still fails in comparison to the latest crop of Intel and AMD CPU's because the SPE's are relatively high latency and underpowered in comparison to a proper core with the x86 architecture.

The Cell is also poor at doing allot of GPU rasterisation tasks which are highly parallel in nature, they would need to basically remake the cell so they can odd Rops, TMU's and more versatile pipelines and cache hirachy to even be able to remotely pull off such a feat.

PC's are also several generations ahead, if you think the PS3 of Xbox 360 has "good" graphics then you are missing out.

N64 Expansion Pack

Sega 32X

Basically every single Sega Add-on

Check the history Sony.

My ps3 has 4 USB ports, so I can use 4 of them simutaneously and have ps5 graphicz

DA POWAH OF DA C3LL!!!!!!!!!!!

(no one has done this in a looooooong time)

But serously, how does this work?? Do they make games run faster or can they actually improve graphics, what about PS3s that don't have the upgrade, will they be able to run new games??

hmmm, I don't think so. Not a good idea IMHO. 

Adding memory is a good idea. The more RAM for the developers to use, the better. However, adding more processing power to an already powerful processor is like adding more water to a dam. What's the point? 

Improve the faults first, then attack the hardware. Please please please hurry up and improve the OS. I'd rather go for that then just getting even more of what I ALREADY HAVE. 

looks like it would add another 512 ram... that would benefit every game released to date.

No it wouldn't.
Game's won't use any more memory than they were designed for.
More memory doesn't make a PC faster, it just makes it so there is allot less disk-swapping.

However if you have 2gb of ram and you are only using at-most 1.5gb, adding another 2gb doesn't suddenly make your computer any more faster, it just allows the computer to run more things at once, or more memory hungry applications, the old Applications won't see any benefit at all unless they were hitting a memory barrier.

A lot of older titles suffer from massive memory leaks which could benefit from more ram as they would have more ram to absorb.

Your first post...ah I remember mine. I said something kinda dumb too. 

Do you really think that he doesn't know that already? The graphics portion of your comment that is. 

However, the GPU vs. Cell comment is a little off. Yes, with a good GPU you can get really reaaaally intense sick graphics. But the Cell can also do the same while still being a processor at the same time. Not bad, IMHO. 

Besides, why would Sony spend millions on creating a powerful processor when they could just get better graphics with a good GPU? If what you said is true. 

If it's a memory leak, then that still won't solve the problem.
It would just take a little longer for the titles to hit the memory barrier, my last point still stands, because once they hit the "expanded" memory barrier it will suffer the exact same issues.
Only patches will solve that issue.

Not convinced this is a good idea. I won't be surprised if this doesn't see the light of day.
