I'm building my first rig and im trying to stay within my $850 budget. I'm wondering if I should just go ahead and buy a card like the 6870 now, or wait a couple of weeks for the 7xxx series to hit shelves for prices to drop.
For an $850 budget total you need to make compromises. Unfortunately if it's for gaming, you really should pick a lower cost CPU/mobo combo like an i3 2120/H55 set in order to get a decent GPU. However, with what you've got, I'm sure if you just save for a month or two you can get a decent 6770, 6790, 550 Ti or better depending on how your finances are doing.
got my i5 for 180, optical for 17, 500gb hdd for 50, mobo for 90. that leaves about 450 for the case, ram, gpu, psu and windows 7. think im doing alright so far. waiting for this price drop to happen so i can search for that final piece.
