I have a budget of £150ish and am in the market for a 4GB decent card. I currently have a MSI R9 270 OC but it only has 2GB and it causes games to lag when I turn up AA or MSAA in games like rainbow 6.
Now, my PSU is a Seaonic 520w and I don't want to upgrade or have a power hungry card in my PC.
What should I go for and which makers also have a decent fan control software like MSI Afterburner ?
