quick nooby question

Can an xbox360 acrade play reglar xbox360 games such as gta 4 , gears of war , graw 2 , force unleashed and etc. Also can the acarde save all these games? I am currently thinking about getting an acrade for my birthday and wanted to know if it is capable . I am not doing live or storing music or movies just games would an acrade be a good buy for me?

thanx in advance

No need to ask the same question twice.

Beat me to it. I just answered "Quick xbox360 noob questions," then I see "quick nooby question." I was like, "Wow, there are a lot of noob questions today...oh wait...it's the same guy...with the same question."
