my carrier has offered me an upgrade from my 9780 but not sure what to get?

thinking about the bold touch or the torch, any recommendations?

is the bold touch basically the same phone as mine with a touch screen?

i feel my current 9780 lacks memory, or is not equipt with sufficient memory, will i run into the same issues with the bold touch or torch?

i dont really know too much about either phone

You need to visit a shop and try them both to see which one you like best. Neither of them are the same as your device.

Also, RIM has a "compare" utility on their website to show differences in specs.

BlackBerry - Compare BlackBerry Smartphones and PDAs at BlackBerry.com

Use the RIM compare utility to weed out devices from your list of possibilities and then go check them out in person. Hands-on is really the only way.
