Hey all, I have an Alienware x51 (the small one) and I know they are limited on what GPUs can be put inside (mainly due to lack of space, etc.), as of right now i am running an Nvidia Geforce GT 545. I am looking to upgrade this one for around 200$ maximum. I am here really just looking to know what GPUs does Nvidia make that are compatible. I've tried looking into for myself, but can't find anything that I believe to be reliable.
Thanks.
