Hi all, Currently I am using a 7+ year old custom built PC (XP) and lately I have been wanting to make the switch to Mac, specifically an iMac. My PC’s specs include an AMD Athlon 64 3000+ CPU, Radeon 9600 128mb GPU, and 1.5 gb of RAM. Since owning the PC, I have had little to no problems save for a blown PSU which is to be expected through years of wear and tear. My reason for considering a switch is that I have been a long time Windows user, and while I’ve had a relatively good experience with it, I would like to make a change. Like mostly everyone, I find the iMac’s design to be minimal, yet strikingly appealing, which makes for quite an attraction to me. My PC’s performance is borderline adequate during intensive single-task work, such as running only Photoshop CS4 without any other programs being open, but becomes sluggish, and sometimes freezes temporarily, when multiple programs and multiple PS files are running simultaneously (multiple tabs of Chrome, iTunes, etc). Some might suggest additional RAM, but the motherboard allows only for 2 GB, thus upgrading is not an option unless I replace the motherboard, which is something I have no interest in doing. The bulk of my computer usage is comprised of internet, Word, Photoshop (large RAW’s and JPEGS) iTunes, and eventually videography once I can upgrade my dSLR. I would like for the iMac to be able to perform these tasks simultaneously, with virtually no lag. With all things taken into consideration, which iMac configuration would best suit my needs? I am a student, thus my budget does not allow for the high-end iMac. I plan to use my discount and purchase during the back to school promotion, so I figure I can save at the most $250-300 with the $100 discount and by reselling the likely iPod touch, which leaves me around $1300-1400 to spend. Will the base iMac be sufficient for my needs, or should I opt for a higher end spec’d iMac, such as an i7 with a beefier GPU. Also, is there a significant difference in terms of performance between the 6750M and the 6770M? Thanks in advance for any and all help.
