You replied at my post a while ago can u tell me weather r7 250 will work with my system it wont bottleneck it? The gt 740 is pcie 3.0 and my mobo is 1.0 so it wont be a huge bottleneck for sure?
Would need to know the motherboard for an exact answer, however:
PCIe increases in maximum bandwidth over time.
PCIe 1.0 1x = 250MB/s PCIe 1.0 16x = 4GB/s 8x = 2GB/s
PCIe 2.0 1x = 500MB/s PCIe 2.0 4x = 2GB/s
PCIe 3.0 1x = ~1000MB/s
Basically any connection is adequate for low end GPUs. PCIe 1.0 4x might be pushing it a little, but this isn't about getting the best possible config. It is about adding a newer GPU to an aging system.
Any improvement is going to be desirable.
When more funds are available you can replace the CPU/Motherboard/Ram and keep the GPU until that becomes underwhelming and so on.
