One, thats not true. They lose performance for any amount of data stored on them. 10% full and its not as fast as if it were blank. Granted at that point it would not be noticeable. But around 50% it is, in benchmarks anyway.
Out of the box, the larger the drive is, the faster it will be then its smaller counter part. Especially with newer SATAIII drives, a 120GB drive is almost as good as two 60GB in RAID0.
Also, again, the more space left un-partitioned, the more space there is for GC to work, keeping the drive performing as well as possible, and adding to the life of the drive.
If you figure 30GB for a full OS install and some basic apps, and maybe a game or two, and leaving 10% extra of the drive un-partitioned, that leaves around 30-32GB free of an 80GB SSD.
2nd, I have not tried BF3 yet, my rig is down at the moment, and it really doesnt seem as great as the hype is for it. For everything else, Ive never seen an issue with 1GB for 1080P or less. And again, I also said that if he didnt want to run everything on all ultra settings with max super AA and whatnot, a 6870 is a perfectly fine gaming card for 1080P for the money.
I never said there was really anything wrong with the ASUS board (other then the CPU_Fan header being bad, and the LLC not being the best). What I said was there is better stuff for the money. Why pay $200 for an ASUS board, when the Gig board with the combo deal I posted is just as good? OCing SNB is CPU based, you will get the same OC on different boards (provided they are complete junk), so there is no point in spending extra money thinking you will get a better OC. Also, all the 1155 boards are 8x8 PCIe lanes at best (except ones with added on chips for that), so again no point in spending more money on it.
