Hi All, After a while of wanting to make the plunge, and waiting too long to get a good deal on a 5,1 I have gotten myself a 2008 Mac Pro 3,1 2x2.8, 32GB RAM , and a 5770 graphics card. I have also gotten myself a 27" Cinema to upgrade the original 23". Besides learning to navigate my way around in Mac OS, I'd like to do some gaming. I think the most challenging thing that I like to play is Wargaming's World of Tanks and World of Warships. To start with, I have ordered a OWC PCIe to 2.5" SATA adapter to mount a new boot drive. I could get a pair of 5472's but I'm not sure the upgrade would be worth it, at least until I know if I like it. RAM is maxed, so nothing I can do there. I kind of want to upgrade the video card but I am not sure which direction to go in, I'm used to Nvidia but it looks like either path is valid. I want to be able to keep the boot screen, so I was thinking something like a flashed r9 280x or a gtx 680-770-970(maybe titan?). At what point are the other parts of the system going to cause a bottleneck that getting a higher tier video card is not worth it? Assuming that DP to mDP adapters work, I need something with either mDP or DP for the Cinema Display. I'm not really sure what my best choice is? I was going through previous posts, but there seems to be a lot of old material and I am not sure which concerns and issues are still valid. Is there anything else I should be thinking about?
