Basically this is my current rig which I've upgraded over time: M4A89GTD Pro/USB3 Ati 5870 8GB Mushkin Phenom II 965be 850W PSU Now I have a sound card etc. but now the thing is, my PC is having huge bsod problems, and the main suspect is the MOBO (SSD/HDDs and RAM have been replaced already, no luck). With this mobo, and it most likely being faulty, there's no point in staying with this socket (the cheapest mobos I found are still way too expensive in my opinion, for that CPU anyway). The thing is, I'm getting a second 5870 for free and my intention was to buy a new 1150 mobo for 80-100€ or so (should be able to find a xfire mobo with that budget) and a i5-4690 (or maybe go for the unlocked one, but I doubt that mobo will do any overclocking). That way my rig would be have the i5 4690 and 2x5870 for only around 300€, how do those two match up? Is crossfire a huge hassle, and how do they work in newer games? I feel like my GPU is still pretty good, even in modern games and mostly it's the CPU that's bottle necking (e.g. PS2 or GW2). Any comments?
