Hi Lx,
Welcome to the UK BOINC Team (UBT for short
)
As Chris and Mark have already implied, our "remit" is to support each and every BOINC project, so no matter which one (or more) takes your fancy, you can be sure that:
1) our team already has members who are (or have been) active on that project
2) the team always strives to help "newbies" understand which projects are perhaps the most worthwhile-
...and hence we can provide info to you about how best to configure your computer and make the most of the processing power you have at your disposal (esp if you have a desktop machine with a ATI/AMD/NVidia based graphics card).
So, pick one or more projects, make sure you "join" our Team on each of the projects website (having logged into your account on) and allow your computer to download some tasks.
Let us know how it goes, and if you have any issues, then feel free to ask away - we've all been "newbies" at some point and gradually we've learnt how to help all the projects and have a bit of fun too.
EDIT: I've found "lexy"'s SETI@home account and the account lists the following processor and OS:
CPU type: ARMv7 Processor rev 0 (v7l) (2 processors)
OS: Android 3.4.5-2708044 (Android 4.4.2)
BOINC version: 7.4.53
Memory: 0.81 GB
So, talking about GPU's and optimising your "PC" for best performance will be a bit limited.
regards
Tim
