hello guys i have a system like Phenom IIx4 940 3 Ghz 550W OCZ fatality PSU 4 gb DDR2 800 mhz rams and hd 4850 GPU. My gpu burned recently so i need to buy a graphics card immediately. I want to buy a r9 270x dual-x or MSI R9 280 Gaming GPU . I know it will be bottlenecked by my cpu but i will change mobo cpu rams in 3-4 months also. and i have 1080p monitor. they say it s not good getting over 256 bit for 1080p so i sud buy a 256 bit card? And it s really bad to get R9 280 cus of much bottleneck over r9 270x even for 3-4 months?Can you help me decide on graphics card for now plz?
