I do it on a daily basis...Tee Hee!.......Add 9 HDR bracketed images .........Use RAW@ 24MP...........stir for one minute in Photomatix-Pro and bake in Adobe CS5 with lots of layers..........Without this torture...... DM is correct as usual
Just to cover home base though Page-file is much like scratch disc usage in Photo-shop....it will always seek out memory first if it's (memory) is available.....If you have a storage disc in the system It won't hurt to allocate 4 or 5 gig towards it,...the important thing is to keep it away from C drive in the unlikely event of "Memory Full" "Flush to Disc"
