Yes the W4300 comes with a low bracket. Keep in mind you will not get full performance of the card since your PCIE is set to x8. However I assume for your needs, that should be OK, since you had no performance issues with FirePro 2270 on the same motherboard, correct?
Thanks for the reply.
The 2270 was originally in a SuperMicro X9SCL (Ivy Bridge) based system that only had x4 & x8 slots so I had to use the 2270 SKU 100-505652 (512MB DDR3, PCIe 2.1 x1) rather than the x16 version. Even in the Ivy Bridge based system it was surprising how well Adobe CC worked with 2 1080p monitors. Not an ideal solution but it illustrates just how little GPU performance is necessary for low to mid range business/creative use as opposed to gaming needs.
I do use a lot of layers in PhotoShop in my workflow but not a lot of filters which would be able to take advantage of OpenCL GPU acceleration.
Though iGFX is more commonly available in newer Haswell & Skylake workstation and server boards based on the E3 Xenon platforms they do not support a 10-bit workflow and so are limited.
I did notice that LightRoom & Photoshop was more "snappier" when I installed a older Diamond HD5670 (1GB GDDR5, PCIe 2.1 x16) as a test to verify operation of a x16 card in an x16 slot with only 8 lanes.
After all is said and done I ended up ordering a W4100 instead of the W4300 which should yield a boost over the HD5670 with the move from 500MBps PCIe 2.X lanes to 980MBps PCIe 3.X lanes. Though the W4300 offers a slightly better value proposition a twice the performance at twice the price I strongly suspect my workflow would not benefit from the additional Stream Processing Units and VRAM. The funds that were saved were used to buy more system memory which PhotoShop will use.
Understood and good luck
