Hello, I have 3 x Mid 2010 Mac 5.1 machines and I am trying to do some upgrades for them. They are https://everymac.com/systems/apple/mac_pro/specs/mac-pro-eight-core-2.4-mid-2010-westmere-specs.html I’ve upped the memory on some and done an SSD and one GPU I do them in different stages so it’s a bit of mix bag. This is what I have at the moment MAC1 High Sierra, new SSD, but old 5770 gpu and ROM MP51.0089.B00 and 32 GB of RAM (I’d like to match it to MAC2 with the 1050Ti.) Currently only office use will be used for Static graphics (Photoshop CC / Indesign CC) MAC2 High Sierra new SSD, Gigabyte 1050TI + 5770 (I left it plugged in in the bottom slot but I didn't plug the power connector in case I need to do any upgrades and I cannot see the boot menu) ROM MP51.0089.B00 and 32 GB of ram MAC3 Sierra, HDD, 5770, 16 GB ram. (ROM MP51.0089.B00) This one I want to use video editing. It will be used for ADOBE premiere pro CC. I got £700 and I would like to get the best GPU for this budget. I want to avoid soldering the PSU so only using the 2x SATA connectors and 2x Mini 6 Pin. What I already have for this mac, new SSD, extra 16 GB of ram, cable 2x Mini 6 Pin to 1x 8 pin connector. My Questions are: 1)MAC3: what GPU to get aka RX580 or 1080(Ti), 2080, what additional cables to I need? Do I need 64 GB of ram or 32 is sufficient? 2)Should I upgrade to Mojave ? What are the benefits? Can someone explain the METAL bit for the gpus ? Will that mean I will be able to use my 1050ti in a boot menu? It seem to not support 5770 ? 3)I keep the old 5770 in the bottom PCI slot, and the new 1050Ti in the one above it (the 1050Ti is choking the fan of 5770 but its not connected unless I am doing upgrades), are both of the bottom PCI slot x16 ? is there any Disadvantage for this ? The 5770 is unplugged I only unplug the 1050ti and plug the 5770 when I need to do rom upgrade or NVIDIA drivers update. I hope someone can help me shed some light into this.
