I'm considering getting my first MacBook Pro - a 17" i7 with 8GB RAM and an SSD. I plan on making this a desktop replacement, coming from a 2.8GHz Core 2 Quad with 8GB RAM and a GTX 260 GPU. I consider the 17" i7 a good trade-off because I mostly under-utilize my desktop (that is, it's not constantly being pushed to its limits under a heavy workload (encoding, compiling, rendering, etc)), and my 24" is the same resolution as the 17" (1920x1200) so I get the same workspace. My concern, though, is whether the 17" i7 will overheat under my typical workload. Here are a few scenarios of how I work to give you an idea... 1) A few instances of Firefox with 30-40 tabs altogether (several videos, some loading, at most one playing, but otherwise the same as above); chat client; email client; possible a torrent app with one or two downloading/uploading. 2) Photoshop with a 50MB interface design (sometimes 2 or 3); Dreamweaver with several files open; one or two instances of Firefox with a dozen or so tabs open on each (a video or two, but mostly news, forums, email and the like); iTunes in the background downloading and/or playing a track; Dropbox; chat client; email client. 3) Maya; Firefox with a dozen or so tabs; iTunes; chat; email. ...so that's what I'm typically doing. I'm not sure how the 17" i7 would handle this. Would the temps run near or above the CPU's threshold for any or all of these cases? Any thoughts? Thanks.
