I am going to Crossfire 2 X1600PRO from HIS for my new rig (yay for arctic cooling), but i still want more performance from my R9550, clocked at 515mhz/280mhz artifacting very rarely, only when i accidentally block airflow to the 80mm fans (yes the cooling is worth more than the card, so what???). So what will give more performance increases? Memory timings may kill my card however, and I haven't yet found any 9600 PRO Bioses that use Infineon 4.0 ns DDR1. Overclocking does help but i am beginning to realise that there might be a lack of voltage, the new 80mm fans, mounted on the stock passive heatsink (with some thick screws; four of them to be exact. The fan sucks air and blows it onto the card's stock heatsink, the fan is mounted over the memory, and GPU. Looking at it, the heat is pumped out towards the sides of the card. Should I Flash (Providing someone find me an Infineon 4.0ns 9600PRO bios), Voltmod, or just leave the card the way it is? NOTE: I can play CS:S at around 40 to 70 fps (when running around 12 bots on the server), higher when online, at 2x FSAA, 4x/8x Antiso, All high settings (without hdr, i get blinded by that shit). Right now, i want much much more performance. Ill put pics up of the card later.
